PROBLEM TO BE SOLVED: To provide a process cartridge and an electrophotographic image forming device capable of surely transmitting driving force to an electrophotographic photosensitive body and improving image quality. SOLUTION: When the process cartridge is attached to a device main body, a cartridge coupling member is fitted to a main body coupling member, so that the driving force for rotating the electrophotographic photosensitive body is received from the device main body. On the other hand, a driving force transmission member for the electrophotographic photosensitive body is engaged with a driving force receiving member for a developing roller, to receive the driving force for rotating the developing roller, from the electrophotographic photoreceptor. Further, magnetic seal members 201 are provided with gaps (g) from the developing roller 9c, to prevent toner from spreading along the magnetic lines of force of the magnetic seal members 201 in the longitudinal direction of the developing roller 9c. Thus, the image quality can be improved. |
