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 (144 a) movable between an electrical connecting position and a retracted position retracted from the electrical connecting position, a displaceable member (147) for moving the output contact, 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 when the process cartridge (B) is inserted into the main assembly (A) of the apparatus (100), the movable operation member (142) is engageable with a fixed engageable member (146) fixed in the main assembly (A) of the apparatus (100) to move relative to the cartridge frame (B1), and is engageable with a displaceable engaging portion (147c) of the displaceable member (147) to move the output contact (144a) from the retracted position to the electrical connecting position against an elastic force of the elastic function member (149), after the engagement with the fixed engageable member (146); 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.
