ABSTRACT:
A process cartridge detachably mountable to a main assembly of an image forming apparatus includes a cartridge frame, an electrophotographic photosensitive member, a processor actable on the electrophotographic photosensitive member, and a cartridge shutter capable of taking a closing position for covering an exposed portion of the electrophotographic photosensitive member exposed from the cartridge frame and an open position for exposing a part of the electrophotographic photosensitive member. The cartridge shutter has a first portion and a second portion which are swingable relative to each other, with the first portion being disposed downstream of the second portion with respect to a movement direction of the shutter toward the open position. The cartridge shutter takes a position above the cartridge frame when the process cartridge is mounted to a mounting position of the main assembly of the apparatus and the shutter takes the open position.
