A process cartridge (B) detachably mountable to a main assembly (A) of an electrophotographic image forming apparatus (100), the main assembly (A) including an output contact (144a) movable between an electrical connecting position and a retracted position retracted from the electrical connecting position, displaceable member (147) for moving the output contact (144a), and an elastic function member (149) for elastically urging the displaceable member (147) to urge the output contact (144a) toward the retracted position away from the electrical connecting position, the process cartridge (B) includes an electrophotographic photosensitive drum (107); process means (108) actable on the electrophotographic photosensitive drum (107); a movable operation member (142) movable relative to a cartridge frame (B1), wherein after the process cartridge (B) is mounted to the main assembly (A) of the apparatus, the movable operation member (142) is displaced by a driving force transmitted from the main assembly (A) of the electrophotographic image forming apparatus (100) to the process cartridge (B), so that movable operation member (142) is engaged with the displaceable member (147) provided in the main assembly (A) of the electrophotographic image forming apparatus (100) to move the displaceable member (147), in interrelation with which the output contact (144a) is moved from the retracted position to the electrical connection position against an elastic force of the elastic function member (149); an input electrical contact (141a) for receiving a voltage for enabling the process means (108) by engagement with the output contact (144a) moved to the electrical connecting position. |
