SHUTTER MECHANISM, CLEANING DEVICE, PROCESS UNIT AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a shutter mechanism for which controlling of a driving device and the exclusive driving device only for opening and closing a shutter member are not necessary.

SOLUTION: The shutter mechanism includes: a rotary body 35 rotating along with an image forming action; an abutting and moving member 36 composed to abut to the rotary body 35 as well as being able to move in a preset direction; and the shutter member 34 composed to open an opening section 1a along with the movement of the abutting and moving member 36. The abutting and moving member 36 is composed to move by friction occurring between the rotating rotary body 35 and the member 36 in the movable direction, so as to be slidable to the rotating rotary body 35 in the movement restricted direction.
