Abstract

A charger has a charging wire that extends in the axial direction and that has one end and another end. The charger is configured to charge the image-bearing member. A cleaning member is movable in the axial direction for cleaning the charging wire. The cleaning member is movable between a first position located on the one end and a second position located on the another end. A removal-restricting portion is movable between the first position and the second position. A developer cartridge is detachably mounted on the image-bearing member cartridge. The removal-restricting portion prevents the developer cartridge from being removed from the image-bearing member cartridge when the cleaning member is in the first position, and allows the developer cartridge to be removed from the image-bearing member cartridge when the cleaning member is in the second position.

Description

[0001] Cross-references to related applications [0002] This application claims priority from Japanese Patent Application No. 2004-374680 filed on December 24, 2004, the entire subject matter of which is hereby incorporated by reference. technical field [0003] The present invention relates to a process cartridge, an image bearing member cartridge and a developing cartridge provided in the process cartridge, and an image forming apparatus equipped with the process cartridge. Background technique [0004] A conventional image forming apparatus such as a laser printer is equipped with a main apparatus body in which a process cartridge can be detachably mounted for easy replacement of a photosensitive drum, toner, and the like. [0005] The process cartridge is composed of a photosensitive member cartridge including a photosensitive drum and a toner cartridge containing toner. After the photosensitive member cartridge and toner cartridge are removed from the main apparatus b...
