Summary:To suppress reduction in cleaning performance when the temperature is low in comparison to a case where a metal roll is used as a counter roll when a roll different from the counter roll arranged so as to be opposed via an endless belt to a blade-like cleaning member being an elastic body is a drive roll.SOLUTION: A cleaning device 60 comprises: a blade-like cleaning member 62 which is arranged such that a tip formed of an elastic body is pressed against an intermediate transfer belt 22 and which cleans a surface of the intermediate transfer belt 22; and a driven roll 65 being the driven roll 65 which is arranged so as to be opposed via the intermediate transfer belt 22 to the cleaning member 62 and is driven to rotate by the movement of the intermediate transfer belt 22, and whose outer peripheral surface is formed of an elastic body.SELECTED DRAWING: Figure 2 【課題】弾性体でブレード状のクリーニング部材に無端状ベルトを介して対向して配置される対向ロールとは異なるロールが駆動ロールである場合であって、該対向ロールとして金属ロールを用いた場合と比較して、低温時にクリーニング性能が低下することを抑制する。【解決手段】クリーニング装置６０は、中間転写ベルト２２に、弾性体で形成された先端が押し付けられて配置され、中間転写ベルト２２の表面をクリーニングするブレード状のクリーニング部材６２と、クリーニング部材６２に、中間転写ベルト２２を介して、対向して配置され、中間転写ベルト２２の移動に従動回転する従動ロール６５であって、外周面が弾性体で形成された従動ロール６５と、を備える。【選択図】図２
