ABSTRACT:
A cleaning apparatus for a photosensitive member of an electrophotographic copying machine is provided. The apparatus comprises a cleaning brush disposed for contact with a photosensitive drum while rotating in order to remove unnecessary developing toner which attaches to the drum, means for moving the cleaning brush into contact with or away from the drum, a striker rod to strike off the toner attaching to the cleaning brush, and trap means for collecting the toner which is removed by the cleaning brush and the striker rod. An arrangement is made to cause an angular movement of the striker rod to change its surface for abutment against the brush in association with the movement of the cleaning brush into contact with or away from the photosensitive drum.
