To provide two lubricant supply units, and even in the configuration, efficiently supply lubricant to a surface of an image carrier from the two lubricant supply units.SOLUTION: A first lubricant supply unit 15 is installed on the downstream side in the direction of rotation of a photoreceptor drum 11 with respect to a cleaning blade 14a, and a second lubricant supply unit 16 is installed on the upstream side in the direction of rotation of the photoreceptor drum 11 with respect to the cleaning blade 14a. A first driving motor 45 (first adjustment means) that adjusts the amount of lubricant supplied to a surface of the photoreceptor drum 11 by the first lubricant supply unit 15, and a second driving motor 46 (second adjustment means) that adjusts the amount of lubricant supplied to the surface of the photoreceptor drum 11 by the second lubricant supply unit 16 are further provided.SELECTED DRAWING: Figure 2 【課題】２つの潤滑剤供給部を設けた場合であっても、２つの潤滑剤供給部から像担持体の表面に効率的に潤滑剤を供給する。【解決手段】クリーニングブレード１４ａに対して感光体ドラム１１の回転方向下流側に第１潤滑剤供給部１５が設置され、クリーニングブレード１４ａに対して感光体ドラム１１の回転方向上流側に第２潤滑剤供給部１６が設置されている。さらに、第１潤滑剤供給部１５による感光体ドラム１１の表面への潤滑剤供給量を調整する第１駆動モータ４５（第１調整手段）と、第２潤滑剤供給部１６による感光体ドラム１１の表面への潤滑剤供給量を調整する第２駆動モータ４６（第２調整手段）と、が設けられている。【選択図】図２
