Patent ID: 7689146

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, said main assembly including a motor, said process cartridge comprising: an electrophotographic photosensitive drum, process means actable on said electrophotographic photosensitive drum; a developer accommodating portion that accommodates a developer for developing an electrostatic latent image formed on said electrophotographic photosensitive drum; a developer supply opening, provided in said developer accommodating portion, that supplies the developer from said developer accommodating portion to said electrophotographic photosensitive drum; a sealing member that unsealably seals said developer supply opening; an unsealing device that unseals said developer supply opening by removing said sealing member from said developer supply opening by receiving a driving force from the motor and acting on said sealing member; and a spacer member that spaces said electrophotographic photosensitive drum and said process means from each other, said spacer member being movable from a spacing position for spacing said electrophotographic photosensitive drum and said process means from each other to a contact position for permitting contact between said electrophotographic photosensitive drum and said process means, wherein said spacer member receives the driving force from said motor by way of said unsealing device to move from the spacing position to the contact position.
