ABSTRACT:
Provided is a process cartridge detachably mountable to a main body of an electrophotographic image forming apparatus having a guide member, including: a cartridge frame; an electrophotographic photosensitive drum; process unit acting on the electrophotographic photosensitive drum; and a projecting portion which is provided in the cartridge frame and, when the process cartridge is mounted to the main body of the electrophotographic image forming apparatus, is guided to the guide member to guide the process cartridge in a mounting direction in which the process cartridge is mounted to the main body of the electrophotographic image forming apparatus, in which: when the process cartridge is mounted to the main body of the electrophotographic image forming apparatus which is conformable in functions of the process cartridge, the projecting portion allows the process cartridge to insert the main body of the electrophotographic image forming apparatus; and when the process cartridge is mounted to a main body of an electrophotographic image forming apparatus which is unconformable in functions of the process cartridge and having different functions, the projecting portion abuts against a main body frame provided in the main body of the electrophotographic image forming apparatus having different functions to prevent mounting of the process cartridge.
