The main assembly includes an output contact movable between electrical connecting and retracting positions, a displaceable member for moving the output contact, and an elastic member for elastically urging the displaceable member to urge the output contact toward the retracted position. The process cartridge includes a drum, a process device actable on the drum, an operating member, a movable operation member operable by the operating member, after mounting the cartridge to the main assembly, to move the displaceable member, in interrelation with which the output contact is moved from the retracted to the electrical connection position against an elastic force of the elastic member, and an input electrical contact for receiving a voltage enabling the process device by engagement with the output contact moved to the electrical connecting position.Field of SearchProcess cartridge unit | |
