PURPOSE:To remove foreign matters stuck to the surface of a photosensitive body without damaging the surface thereof by forming the top of a brush bristle in the shape of a loop and separating a twisting part provided on a part where the twist of plural fibers forming one loop appears on a tighting side when the twist rubs the surface of the photosensitive body from an abutting position. CONSTITUTION:A rubbing member is composed of a brush roller 14, a large number of bristles of the brush roller 14 are made of plural fibers with the twisting part 20, and the loop 18 is provided on the top. The twisting part 20 is provided out of the abutting point where the surface of the photosensitive body 1 abuts on the rubbing memeber 14, and the twisting position appearing on the tight side when the member rubs the surface of the photosensitive body 1 is arranged aparted by the distance that the phososensitive body does not move to the abutting point at the time of rubbing away from the abutting point. The top of the loop 18 of bristles 17 formed with twisted fibers of the brush roller 14 is brought into contact with the surface of the photosensi tive body 1, and a large number of single fibers composing the twisted fibers sequential ly are brought linearly into contact with the surface of the photosensitive body 1 and polish the body. Thus, foreign matters stuck to the surface of the phososensitive body 1 can be removed without damaging the surface of the photosensitive body 1.
