Patent ID: 7315706

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the main assembly including an output contact movable between an electrical connecting position and a retracted position retracted from the electrical connecting position, a displaceable member configured and positioned to move the output contact, and a main assembly elastic function member configured and positioned to elastically urge the displaceable member to urge the output contact toward the retracted position away from the electrical connecting position, said process cartridge comprising: an electrophotographic photosensitive drum; a charging member configured and positioned to electrically charge said electrophotographic photosensitive drum; a movable operation member which is movable between a standby position and an operating position retracted from the standby position and includes a first engaging portion and a second engaging portion, wherein when said process cartridge is inserted into the main assembly of the apparatus, said first engaging portion is engageable with a fixed engageable member fixed in the main assembly of the apparatus to move from the standby position to the operating position, and in a state in which said movable operation member is located at the operating position, said second engaging portion is engageable with a displaceable engaging portion of the displaceable member to move the output contact from the retracted position to the electrical connecting position against an elastic force of the main assembly elastic function member, after the engagement with the fixed engageable member; and an input electrical contact configured and positioned to receive a voltage for enabling said charging member by engagement with the output contact moved to the electrical connecting position.
