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.

摘要： A cleaning device includes at least one first cleaning member that removes residual substances that remain on a surface of an endless belt by being in contact with the surface of the endless belt while rotating in a direction that is opposite to a movement direction in which the endless belt moves; a second cleaning member that is brought into contact with and separated from the surface of the endless belt at a predetermined timing and removes the residual substances that remain on the surface of the endless belt; and a switching unit that switches a rotation direction of the first cleaning member to a direction the same as the movement direction of the endless belt when the second cleaning member is brought into contact with the surface of the endless belt and cleans the surface.

摘要： A cleaning device includes a first cleaning member, a first opposing member, a second cleaning member, a second opposing member, and a pressing member. The first and second cleaning members clean an outer surface of a belt member by coming into contact with the outer surface. The first and second opposing members are in contact with an inner face of the belt member at positions that are opposite the first and second cleaning members. The pressing member is disposed between the first and second opposing members and is in contact with the outer surface of the belt member. The pressing member presses a portion of the belt member that is located between the first and second opposing members from an outer surface side of the belt member toward an inner face side of the belt member.
