PROCESS CARTRIDGE AND DEVELOPING CARTRIDGE IMPROVING ACCURACY OF DECIDING POSITION TO MAIN ASSEMBLY BODY OF ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS REMOVABLY MOUNTING THE PROCESS CARTRIDGE AND DEVELOPING CARTRIDGE
PROCESS CARTRIDGE AND DEVELOPING CARTRIDGE IMPROVING ACCURACY OF DECIDING POSITION TO MAIN ASSEMBLY BODY OF ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS REMOVABLY MOUNTING THE PROCESS CARTRIDGE AND DEVELOPING CARTRIDGE
PURPOSE: An electrophotographic image forming apparatus, a process cartridge, and a developing cartridge are provided to easily and reliably mount a developing cartridge and a process cartridge at a main assembly body of an electrophotographic image forming apparatus. CONSTITUTION: A developing element develops an electrostatic latent image formed on an electrophotography photo conductor drum. A first protrusion is protruded from a frame, being combined with a first cartridge position deciding part of a main assembly body to accurately place a developing cartridge(4) when the developing cartridge is mounted at the main assembly body. A second protrusion is protruded from the frame, being combined with a second cartridge position deciding part of the main assembly body so as not to rotate the developing cartridge centering on the first cartridge position deciding part when the developing cartridge is mounted at the main assembly body. A cartridge guide member(354) is protruded from the frame, and guides the developing cartridge by contacting the developing cartridge with a cartridge guide part of the main assembly body. When the developing cartridge is mounted at the main assembly body, the cartridge guide member is pressed in direction that the cartridge guide member contacts with a second cartridge position deciding part.
