Summary:PROBLEM TO BE SOLVED: To provide a cleaning device configured to prevent toner or an additive from being fixed at an edge part of a cleaning blade, with a comparatively simple configuration, without increasing cost and size of the device, a process cartridge, an image forming apparatus, and the cleaning blade.SOLUTION: During non-image formation, when "reverse rotation mode" for moving a photoreceptor drum 11 (image carrier) in an opposite direction is executed, a second contact section different from a first contact section in a cleaning blade 15a comes into contact with the photoreceptor drum 11, thereby increasing vibration of the cleaning blade 15a as compared with a case of moving the photoreceptor drum 11 in a forward direction. 【課題】装置が高コスト化・大型化することなく、比較的簡易な構成で、クリーニングブレードのエッジ部にトナーや添加物などが固着しにくい、クリーニング装置、プロセスカートリッジ、画像形成装置、及び、クリーニングブレードを提供する。【解決手段】非画像形成時において感光体ドラム１１（像担持体）を逆方向に走行させる「逆回転モード」が実行されるときに、クリーニングブレード１５ａにおける第１当接部とは異なる第２当接部が感光体ドラム１１に当接して、感光体ドラム１１を正方向に走行させたときに比べてクリーニングブレード１５ａが大きく振動するように構成している。【選択図】図４
