When performing a copying operation in this copying machine, first, transfer paper 1 is selected from a selected cassette or tray.
0 is fed by the feed roller 13, passes through the communication section 14 between the feed unit 1 and the image forming unit 2, and is transported on the transport path A. Then, the sheet is conveyed to a position facing the photoconductor 21 by the registration roller 28 on the conveyance path A. On the other hand, the originals 42 stored on the original platen 41 of the ADF 4 are transported one by one along the transport path B and placed in the original reading area 4b, and in this state, the image reading unit 3 reads the original image. . As a result, a laser beam is emitted from the laser writing unit 23 of the image forming unit 2 and is radiated via the mirror 23a onto the surface of the photosensitive member 21 whose surface is uniformly charged by the charger 22 to form an electrostatic latent image. It is formed. Thereafter, the latent image is developed by the developing device 24 to become a toner image, and the transfer roller 25 transfers the toner image to the transfer paper 10 side. The transfer paper 10 to which the toner image has been transferred is fixed on the surface by the fixing device 26, and is discharged onto a discharge tray 29. The toner remaining on the photoconductor 21 after the transfer is removed by the photoconductor cleaning device 27. The illustrated device performs not only the laser writing from the laser writing unit 23 based on the read signal from the image reading unit 3 but also
The laser writing can be performed based on an external input signal.

The copying machine shown in FIG. 1 has the image erasing unit 5 as described above, and removes the toner from the transfer paper 10 on which the toner is adhered to form the image, so that the copying machine can be reused. Can be The image erasing unit 5 includes:
A release liquid is applied to the transfer paper 10 to be reproduced, and the transfer paper 10
And a toner peeling unit 52 for heating the wet transfer paper 10 and peeling off toner adhered to the surface of the transfer paper 10. Further, on the left side of the image erasing unit 5, a paper feeding unit 53 for feeding the transfer paper 10 to be reproduced by the image erasing unit 5 is provided.

The transfer paper 10 mounted on the paper supply unit 53 is
Paper is fed into the image erasing unit 5 one by one by a transport signal issued at a predetermined timing. The transfer paper 10 fed to the image erasing unit 5 is transported along the transport path C, and the wetting unit 51 applies a release liquid.

The toner is pressed by the pressure roller 523 and the toner on the transfer paper 10 is transferred onto the peeling member 522.
When the amount of the liquid applied to the transfer paper 10 by the wetting unit 51 is small, the heat of the toner release unit 52 causes the moisture of the release liquid applied to the transfer paper 10 to evaporate, and the transfer paper 10 is dried. In this state, the toner is discharged from the toner peeling unit 52. Then, the transfer paper 10 is collected in the above-described paper feed cassette 12a along the transport path C, and is used again for copying. The toner adhered to the peeling member 522 is removed by the cleaning device 523 and collected in the waste box 524.

The image forming apparatus according to the present embodiment has such a configuration that an image whose image quality is deteriorated by the steam generated in the image erasing unit 5 can be prevented from being formed in the image forming unit 2. Has adopted.
Hereinafter, this configuration will be described in detail. In this image forming apparatus, the image forming unit 2 and the image erasing unit 5 are used to prevent the vapor generated in the image erasing unit 5 from entering the image forming unit 2.
And a partition 101 that blocks the space between the two. This makes it difficult for the steam generated in the image erasing unit 5 to enter the image forming unit 2. For this reason, as the humidity of the image forming unit 2 increases, the charge amount due to corona discharge decreases, and the difference in density between the image area where the toner adheres and the non-image area where the toner does not adhere on the transfer paper 10 decreases. Can be prevented. Also,
When the humidity of the image forming unit 2 is increased, a lightning strike is easily generated in a transfer portion for transferring the toner image, and it is possible to prevent the toner from being easily scattered. Therefore, it is possible to prevent an image from deteriorating due to an increase in the humidity of the image forming unit 2, thereby preventing an image with deteriorated image quality from being formed.

Further, when the heat generated in the image erasing unit 5 is transmitted to the image forming unit 2 and becomes high temperature, there is a possibility that the electronic parts and the like are deteriorated. In the copying machine according to the present embodiment, by providing the partition wall 101, it is possible to prevent the heat generated in the image erasing unit 5 from being transmitted to the image forming unit 2 by convection. This makes it difficult for heat to be transmitted to the image forming unit 2, so that the temperature does not easily become high, and deterioration of the electronic components and the like can be prevented.

The partition 101 is preferably made of a rust-proof material, for example, a material such as stainless steel or resin. Thus, the partition 101 can be prevented from being rusted by the steam generated in the image erasing unit 5.

Further, if at least a part of the partition wall 101 is made of a heat insulating material so as to shut off heat between the image forming unit 2 and the image erasing unit 5, the heat generated in the image erasing unit 5 is generated. It is possible to prevent heat from being transmitted to the image forming unit 2 by heat conduction. Specifically, the partition 101 has a structure including one or more layers,
At least one of the layers may be made of a heat insulating material, for example, glass wool. With such a configuration, it is possible to prevent the heat from being transmitted to the image forming unit 2 by heat conduction, and to more effectively prevent deterioration of electronic components and the like.

Here, it is difficult to provide a partition 101 that can completely block the air in the image erasing unit 5 whose humidity and temperature have become high due to the generation of the steam and heat from flowing into the image forming unit 2. It may be. For example,
In the illustrated copying machine, a transfer paper discharge port 54 is provided between the image erasing unit 5 and the paper feeding unit 1 in order to discharge the transfer paper 10 reproduced by the image erasing unit 5 to the paper feeding unit 1. ing. Therefore, the image erasing unit 5
It is also conceivable that the air inside flows into the image forming unit 2 from the outlet 54 via the paper feeding unit 1.
Even when the transfer paper discharge port 54 is not provided, the partition wall 101 is provided so that the air can be completely shut off.
It is difficult to construct the device, and it is conceivable that air leaks from a gap between the partition 101 and the housing of the device. In the copying machine according to the present embodiment, the image erasing unit 5
Is lower than the pressure of the image forming unit 5. Specifically, a fan 102 is provided on the wall surface of the image erasing unit 5 as an exhaust means for exhausting the air in the image erasing unit 5 out of the apparatus. As a result, a flow of air is generated as shown by a white arrow in the drawing, and the air in the image erasing unit 5 is discharged out of the apparatus, and the pressure of the image erasing unit 5 is reduced.
For this reason, the air pressure in the image erasing unit 5 provided with the fan 102 is lower than the air pressure in the image forming unit 2 and the sheet feeding unit 1 provided in communication with the image forming unit. As a result, air flows from the image forming unit 2 or the sheet feeding unit 1 provided in communication with the image forming unit toward the image erasing unit 5 at the discharge port or the gap. Therefore, the air of the image erasing unit 5 having high humidity and temperature
It is difficult to flow into the image forming unit 2 directly from the image erasing unit 5 or through the sheet feeding unit 1. Therefore, it is possible to further prevent the image deterioration due to the high humidity of the image forming unit 2 described above. Further, it is possible to further prevent deterioration of electronic components and the like due to the high temperature of the image forming unit 2.

The copying machine according to the present embodiment employs a configuration in which at least one of the image forming unit 2 and the image erasing unit 5 is provided with a dehumidifying unit. In the illustrated apparatus, a dehumidifier 103 such as silica gel is disposed in the image forming unit 2 as a dehumidifier. Thereby, dehumidification is performed in the image forming unit 2 to prevent the humidity in the image forming unit 2 from becoming high, and it is possible to further prevent image deterioration due to the high humidity in the image forming unit 2. it can. If the image erasing unit 5 is provided with the dehumidifying means, the humidity generated in the image erasing unit 5 is less likely to increase due to the steam generated in the image erasing unit 5, so that the humid air enters the image forming unit 2. It becomes difficult to do. Thereby, it is possible to prevent the humidity inside the image forming unit 2 from becoming high, and to prevent the image deterioration due to the high humidity inside the image forming unit 2.

As described above, the transfer paper 1 to be reproduced is provided in the image removing unit 5 of the copying machine according to the present embodiment.
A wetting unit 51 for applying a stripping liquid to the cleaning unit 0 is provided. In the image removing unit, a stripping solution circulates between a liquid supply device (not shown) for supplying the stripping solution to the wetting unit 51 and the wetting unit 51, and a liquid leaking out of the stripping solution for some reason. May occur. Therefore, in the present embodiment, a configuration in which the image forming unit 2 is disposed above the image erasing unit 5 is employed. Thus, even if a liquid leak occurs, it is possible to prevent the inside of the image forming unit 2 from getting wet. Therefore, it is possible to prevent the transfer paper 10 from getting wet due to the inside of the image forming unit 2 causing a jam or the like, and the shortage of the charging unit to deteriorate the image quality. Further, in the copying machine according to the present embodiment, at least one of the one or more control devices for controlling the operation of the equipment in the apparatus is connected to the wet unit 51.
It adopts a configuration that is arranged above. Thus, in the event that a liquid leak occurs in the wetting unit 51, it is possible to prevent the at least one control device from getting wet and not operating normally. In the illustrated device, a control unit 55 on which all of the control devices for controlling the operation of the devices in the device is mounted above the wetting unit 51. As a result, even if a liquid leak occurs in the wetting unit 51, the control device mounted on the control unit 55 is wet and the image forming unit 2 and the image erasing unit 5 do not operate normally. Can be prevented.

Further, in the copying machine according to the present embodiment, the image forming unit 2 is provided with a humidity sensor 104 as humidity detecting means for detecting humidity. When the humidity of the unit 2 becomes equal to or higher than a predetermined humidity, a configuration is provided in which a notification unit that notifies a user is provided. As the notification means, for example, a display panel (not shown) on the upper surface of the apparatus can be used. Accordingly, when the humidity in the image forming unit 2 increases and there is a possibility that the image is deteriorated, it is possible to prevent the user from forming a useless copy, that is, an image with deteriorated image quality. When the humidity of the image forming unit 2 becomes equal to or higher than a predetermined humidity based on the detection result of the humidity sensor 104 instead of or in addition to the notification unit, the image forming operation of the image forming unit 2 is prohibited. Prohibition control means may be provided.
For example, an image forming control unit (not shown) that controls the operation of the image forming unit 2 may have a function as the prohibition control unit. Thereby, when the humidity in the image forming unit 2 becomes high and there is a possibility that the image is deteriorated, the image forming operation is prohibited, and the user is prevented from forming a useless copy, that is, an image with deteriorated image quality. Can be prevented.

Although the above embodiment is an example in which the present invention is applied to an electrophotographic copying machine, the present invention is also applicable to a facsimile, a printer, and the like.
