摘要： A cleaning device includes first to third cleaning members that clean a surface of an endless belt that is looped over rollers including a driving roller. The first cleaning member is brought into contact with and separated from the surface at a predetermined timing. The second cleaning member is disposed upstream of the first cleaning member and downstream of the driving roller in a movement direction of the endless belt. The second cleaning member is in contact with the endless belt so as to prevent a tension variation of the endless belt caused by the first cleaning member from affecting the driving roller. The third cleaning member is disposed downstream of the first cleaning member. A contact state in which the third cleaning member is in contact with the endless belt is switched from a first contact state to a second contact state so as to reduce the tension variation.
