DEVELOPING DEVICE, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE

PROBLEM TO BE SOLVED: To easily connect a developer storing frame body and a developing frame body without generating any deformation, and to reuse both frame bodies by making the developer storing frame body and the developer frame body attachable or detachable. SOLUTION: In a developing device D, a connecting part of the developing frame body 10f with the developer storing frame body 10a or all the part is constituted by a metal frame body. And also in a process cartridge B, a connecting part of a developing frame body 10f with a developer storing frame body 10a or all the part is constituted by a metal frame body. The electrophotographic image forming device is structured with a loading means so that the process cartridge B is attached or detached freely.
