ABSTRACT:
A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The main assembly includes an output contact movable between electrical connecting and retracted positions, a displaceable member for moving the output contact, and an elastic function member for elastically urging the displaceable member to urge the output contact toward the retracted position. The cartridge includes an electrophotographic photosensitive drum, a process device actable on the drum, and a movable operation member engageable with a main-assembly fixed engageable member and with the displaceable member to move the output contact from the retracted to the electrical connecting position against the bias of the elastic function member, in interrelation with the movement of the displaceable member, after the engagement with the fixed engageable member when the cartridge is inserted into the main assembly. The cartridge also includes an input electrical contact.
