Abstract
An intermediate transfer device includes: an endless belt that circulates, receives transfer of a toner image at a first transfer position, and holds the toner image until the toner image reaches a second transfer position at which the toner image is transferred to a transfer receiver; a first cleaning unit that is disposed downstream of the second transfer position and upstream of the first transfer position in a circulation direction of the belt and removes residual toner from the belt after transfer; and a second cleaning unit that is disposed downstream of the first cleaning unit and upstream of the first transfer position in the circulation direction and removes residues from the belt after removal by the first cleaning unit, in which the second cleaning unit includes: a contact cleaning part that extends in a width direction intersecting the circulation direction and is in contact with the belt; and a support guide receiving part that supports the contact cleaning part, and receives a guide for attachment to and detachment from an image forming apparatus main body by sliding in the width direction.
