Description

Detailed Description of the Invention (Technical Field) This invention relates to a toner replenishment method in a still
In particular, it is necessary to use a toner cartridge to replenish toner to the toner replenishing device attached to the image device (also referred to as the image device) 1, which uses toner to form an electrostatic latent image formed on a supporting member. I will follow the method of

(Prior art) In an electrophotographic camera or an electrostatic recording device, an electrostatic layer formed on a full 144 carrier such as a photoreceptor or electrostatic material is coated with colored fine particles called toner. ul
The toner that is imaged is a toner that is called xeria.
There are cases where it is used in combination with grains 7 for stirring the festival charge, and cases where it is used alone.The former is called a three-component developer, and the latter is called a one-component developer. . In any developer, toner is consumed by developing an electrostatic latent image, so toner needs to be replenished into the developing device at regular VrC or as needed.

Toner may be replenished into the developing device face-to-face, or it may be replenished via a toner replenishing device.

The latter toner replenishing device has a toner concentration detecting device (+iii) installed in the developing device and detects it iQ Jim';
VC is used when replenishing toner and/or when replenishing partially supplied toner uniformly in the longitudinal direction of the developing device. 1. When using a cartridge, vc is used. , Normally, a toner replenishment device is required because it is a partial replenishment, but the toner replenishment device can be omitted by diagonally arranging a simple sink plate with a replenishment opening in the longitudinal direction of the developing device. There is.

In most conventional toner cartridge replenishment methods, the first step is to peel off the seal on the toner cartridge and then turn the toner cartridge lip upside down and set it in the replenishment port. In this method, it is troublesome to remove the sealing sole, and when the toner cartridge 7 is set in the replenishment port, the toner may scatter to the outside and contaminate the inside and outside of the machine.

(Object of the Invention) Therefore, an object of the present invention is to provide an improved toner replenishment method using a toner cartridge that makes replenishment work simple and easy and does not cause toner scattering.

In the toner replenishment method according to the VC of the present invention, an inner lid is provided at the entrance of the toner cartridge, and when this entrance is inserted into the toner replenishment port, the inner lid of the toner cartridge is opened by a protruding bottle provided in the toner replenishment port. It is removed inwardly so that the toner inside flows into the toner supply port.

Hereinafter, the present invention will be explained with reference to the accompanying drawings.

(Structure of the Invention) As shown in Figure 1, the toner cartridge according to the present invention includes a transparent bottle 3 for storing replenishment toner 2'f, and a transparent bottle 3 provided inside the slightly narrowed inlet 3a. It consists of an inner cover 4 and an outer cover 5 provided outside the inner cover 4. The inner lid 4 has an inverted cap shape, and a plurality of elastic tubes 48 are provided at the top of the inner lid 4 so that the tip thereof is located in a range larger than the entrance diameter of the bottle 3 and smaller than the diameter of the main body thereof. ing. Both the inner lid 4 and the outer lid 5 are hard enough to be removed by hand and have the same hardness as the bottle 3, and the inner lid 4 mainly seals the toner during normal transportation.
An outer cover 5 is provided to prevent toner from scattering in the event that the inner cover 4 comes off, and to prevent dust from adhering to the inner cover 4 when the inner cover 4 is normally opened.

To replenish toner using such a toner cartridge L, first remove the outer cover 5'f, shake the bottle 3 well while changing the posture of the bottle 3, and then remove the toner 2 inside.
(1 + total sex increase. Next, turn bottle 3 upside down and its population 3
a into the toner supply lower of the toner supply device 6, as shown in FIG. The supply lower is covered by Cover 8 in Nishinomiya. On the inside of the toner replenishment lower, an elastic packing 9 made of a soft foam material whose inner diameter is slightly smaller than the outer diameter of the inlet 3a of the bottle 3 is disposed. Closely,
This prevents toner from scattering to the outside of the insertion section.

A support plate 1o is provided below the gasket 9, and a protruding bottle 11 rises from the center of the support plate 1o. The tip of this protruding bottle H pushes up the inner lid 4 of the bottle 3, and the toner 2 in the bottle 3 is replenished into the L-toner cuff supply device 6. Therefore, the height of the protruding bottle 11 is such that its tip presses the inner lid 4 of the inserted bottle 3, creating a space between its outer periphery and the bottle 3, from which the toner 2 flows out. determined to be possible. Since the bottle 3 is transparent, it is possible to visually confirm the decrease in the amount of toner 2 inside, and all the toner in the bottle 3 is removed by the toner replenishing device f381? :
After confirming that it has been refilled, pull out bottle 3 from the replenishment lower. At this time and when the protruding bottle J] pushes up the inner lid 4, due to the pressure of the bottle]]! In order to prevent the deformed inner lid 4 from falling into the toner replenishing device 6, the inner lid 4 is provided with a plurality of holes 4a.

Pull out bottle 3 from the supply lower and place cover 8 on the supply lower.
When the toner is covered, the toner replenishment process is completed.

On the other hand, the toner supplied to the toner replenishment device 6 is agitated in the tank section 2 by an agitator 13 together with other toner in the p tank section J2, and then replenished into the developing device J5 by the toner supply roller 14. Ru. An elastic packing J6 such as a soft foam material is provided at the joint between the toner replenishing device 6 and the developing device J5 to prevent the toner from scattering to the outside. is in contact with the roller 14 to clean the toner adhering to the roller 14.

The toner car 1 cartridge insertion section J8 has approximately the same size as the bottle 3, and the tank section 12 extends in the longitudinal direction of the developing device J5 to approximately the same length. Therefore, the toner supplied from bottle 3 is partially biased,
It is made uniform by the agitator 13 and is applied to the roller 14.
:lJ7. The image device 15 can be uniformly replenished. A screw conveyor type agitator kff may be used in place of the agitator 13. Further, if a simple sink plate such as the one shown in the front is not used, toner may be replenished directly from the bottle 3 to the developing device 5.

(Effects of the Invention) As described above, the toner replenishment method of the present invention has the following advantages:
Toner can be replenished easily by simply inserting the skewer [1-kurtorishi] into the toner replenishing port, that is, with one touch, and without toner scattering. If a toner cartridge lip prevents the toner cartridge from falling out, even if the inner lid is deformed when the toner cartridge lip is inserted, it will not fall into the toner supply port l/c.
