ABSTRACT:
A separation unit includes separation pawls for separating paper from a photosensitive drum, and a second shaft for supporting the separation pawls. Each separation pawl has a mounting hole extending therethrough and a slit opening the mounting hole. The second shaft has a mounting portion which cannot pass through the slit and a chamfered portion which is formed continuous with the mounting portion. The portion of shaft where the chamfered portion is formed can pass through the slit. An annular bush is loosely fitted on the second shaft so as to be pivotal and movable from the mounting portion to the chamfered portion. The bush is detachably fitted in the hole of the separation pawl and supports the separation pawl. A holder is attached to the second shaft so as to regulate the movement of the bush toward the chamfered portion of the second shaft when the pawl is used, and to allow the movement of the bush toward the chamfered portion of the second shaft when the pawl is attached/detached.
