Abstract:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, said process cartridge comprising:an electrophotographic photosensitive member; a developing member for developing an electrostatic latent image formed on said electrophotographic photosensitive member; a developing device frame including a first frame portion supporting said developing member and a second frame portion having a developer accommodating portion for accommodating a developer to be used for developing the electrostatic latent image by said developing member; first and second electroconductive portions disposed to be spaced from each other to detect, by the main assembly of the apparatus, a remaining amount of the developer in said process cartridge; a cartridge contact electrically connectable with the main assembly of the apparatus when said process cartridge is mounted to the main assembly of the apparatus, said cartridge contact being disposed in said second frame portion; a contacting electrode electrically connected with said cartridge contact, said contacting electrode being disposed in said second frame portion; a first electroconductive portion contact electrically connected with said first electroconductive portion, said first electroconductive portion contact being disposed in said first frame portion; and a first connecting portion and a second connecting portion, provided in each of said first frame portion and said second frame portion, wherein said first connecting portion and said second connecting portion on each of said first frame portion and said second frame portion are disposed to be spaced from each other with respect to a longitudinal direction of said first frame portion and said second frame portion, and wherein said first electroconductive portion contact and said contacting electrode contact each other between said first connecting portions and said second connecting portions.
