PURPOSE:To prevent a shutter to protect a photosensitive body of the processing cartridge from being detached from this cartridge. CONSTITUTION:The opening/closing of a cover 52 is carried out by rotating this cover 52 with rotational supporting points as the center. One of these supporting points is a circular engagement hole 60 and the other is an engagement hole 61 with a slit. The latter hole 61 is provided on the opposite side as a driving pin receiving the opening force provided on the shutter. Thus, since the side receiving the drive is the circular hole 60, the supporting point is not deviated and, on the other hand, because the other one is the hole with the slit 61, the assembly work is facilitated. |
