Abstract

An electrophotographic image forming apparatus includes a removably mounted process unit containing a photosensitive member and process units. A movable cover is connected to the process unit and shields an area of a periphery of the photosensitive member. The movable cover is caused to retract from its shielding position in response to rotational movement of the photosensitive member.
