Abstract:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:an electrophotographic photosensitive drum; a developing member for developing an electrostatic latent image formed on said electrophotographic photosensitive drum; a developer frame having a developer accommodating portion for accommodating a developer to be used for developing the electrostatic latent image by said developing member, wherein said developer frame is provided with a developer supply opening for supplying the developer accommodated in said developer accommodating portion toward said developing member; a connecting member mounted to said developer frame, said connecting member being provided with a connecting member opening opposed to said developer supply opening; a drum frame supporting said electrophotographic photosensitive drum; and a developing frame supporting said developing member, said developing frame being movably connected with said developer frame by a flexible seal, wherein said developing frame is provided with a developer receiving opening for receiving the developer having passed through said developer supply opening, wherein said flexible seal is provided with a first opening and a second opening, wherein said first opening is opposed to said developer supply opening and said connecting member opening, and said second opening is opposed to said developer receiving opening, wherein said flexible seal is stuck on said connecting member at a periphery of said first opening, and is stuck on said developing frame at a periphery of said second opening, and wherein said flexible seal is made of a sheet which is folded back such that said first opening and said second opening are opposed to each other, and ends of surfaces of the sheet which are opposed to each other as a result of folding are stuck to each other.
