PROBLEM TO BE SOLVED: To more improve the cleaning performance of a cleaning apparatus for a charging roller and the durability of the cleaning apparatus. SOLUTION: Regarding the cleaning apparatus for cleaning the charging roller 30 for charging the surface of a photoreceptor drum 20 while rotating in contact with the photoreceptor drum 20, the cleaning apparatus includes: a cleaning brush 100 that extends in the rotating shaft direction of the charging roller 30, for brushing-cleaning the surface of the charging roller 30 while rotating in contact with the surface of the charging roller 30; a rotational driving mechanism 110 of rotating the cleaning brush 100 with a circumferential velocity difference from the charging roller 30; and a thrust driving mechanism 104 for reciprocatively moving the cleaning brush 100 in the rotating shaft direction of the charging roller 30 while making the cleaning brush 100 rub the surface of the charging roller 30.
