Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings.

[0035] (overall structure)

[0036] 1 to 10 illustrate the overall configuration of an electrophotographic image forming apparatus according to the first to fifth embodiments of the present invention and an attachment / detachment guide mechanism serving as an attachment guide for the process cartridge. In the following description, the longitudinal direction of the process cartridge refers to the direction intersecting the direction in which the cartridge is mounted on the apparatus body (approximately perpendicular direction), is parallel to the plane of the recording medium, and is intersecting (approximately perpendicular) to the conveying direction of the recording medium. ) direction. In addition, left and right refer to right or left when the recording medium P is viewed from above in the conveyance direction of the recording medium. In addition, the upper surface of th...

Abstract

When an improper cartridge which does not match in function with the main body of the apparatus is wrongly inserted, a cam portion for opening and closing a shutter comes into engagement with a wrong insertion preventing engagement portion in the opening portion of the main body of the apparatus and the shutter is opened, whereby the wrong insertion of the cartridge is blocked. In the case of a proper cartridge, it is inserted without the shutter being opened in the opening portion of the main body of the apparatus, and with the operation of closing an openable and closable member, the cartridge is inserted into the inner part of the main body of the apparatus together with a moving guide and the shutter is opened at a proper position.

Description

technical field [0001] The present invention relates to an electrophotographic image forming apparatus and a process cartridge. [0002] Here, a process cartridge is used as a processing device, and a charging device, a developing device, or a cleaning device and an electrophotographic photoreceptor are integrated into a cartridge so that the cartridge can be attached to and detached from the main body of the electrophotographic image forming apparatus. Alternatively, as the processing device, at least one of the charging device, the developing device, and the cleaning device is integrated with the electrophotographic photoreceptor so that it can be attached to and detached from the main body of the electrophotographic image forming apparatus. In addition, it also refers to a processing device in which at least a processing device, a developing device, and an electrophotographic photoreceptor are integrated into a box so that they can be attached to and detached from the body ...
