Summary:PROBLEM TO BE SOLVED: To uniformly and stably clean a photoreceptor drum.SOLUTION: A pressure member 23 is arranged on the side facing a photoreceptor drum 131 with a cleaning roller 21 therebetween. The pressure member 23 is arranged to press the cleaning roller 21 in a direction to a position where the cleaning roller 21 and the photoreceptor drum 131 are in pressure contact with each other. The arrangement can prevent separation of the cleaning roller 21 and the photoreceptor drum 131 even when the center part of the cleaning roller 21 is deflected.SELECTED DRAWING: Figure 2 【課題】感光体ドラムを均一且つ安定的にクリーニングすること。【解決手段】クリーニングローラー２１を挟んで感光体ドラム１３１と対向する側に押圧部材２３を配置する。押圧部材２３は、クリーニングローラー２１を、クリーニングローラー２１と感光体ドラム１３１の圧接位置の方向へ押圧するように配置する。こうすることで、クリーニングローラー２１の中央部が撓んでも、クリーニングローラー２１と感光体ドラム１３１が離間することを防ぐことができる。【選択図】図２
