Claims

[Claims for Utility Model Registration] An image forming apparatus includes a device for exposing an original to light above the inside of the main body, and a document conveying device having a conveying means that rotates in either forward or reverse directions on the upper surface of the apparatus main body, After a document inserted from the document insertion section side of the document conveyance device passes through an exposure position by rotating the conveyance means in the normal direction and is exposed, the document is placed on the downstream side of the device main body in the document conveyance direction. A first image forming mode in which the guide member discharges the document from above the document feeder toward the document insertion section, and the document housed in the carrier sheet.
A second step that transports the document together with the carrier sheet to an exposure position and exposes it by rotating the transport means in the normal direction, and after the exposure is completed, transports the original document reversely toward the document insertion section by rotating the transport means in the reverse direction.
In the document moving type image forming apparatus, the document guide member is configured to move the document from the document feeder so that the document is inserted above the document feeder. The document guide member is configured to be in either a guide state in which the document is guided toward the document insertion section or a guide release state in which the document is not guided toward the document insertion section, and the document guide member is guided when the second image forming mode is set. A document moving type image forming apparatus characterized in that it is set in a released state.
