Abstract
A belt cleaning device includes a cleaning roller, a backup roller, and a roller-pressing-state setting mechanism. The cleaning roller is disposed in confrontation with a surface of a belt. The backup roller is disposed in confrontation with the cleaning roller with the belt interposed between the cleaning roller and the backup roller. The roller-pressing-state setting mechanism selectively sets a state of the backup roller to a first state in which the backup roller is pressed against the cleaning roller via the belt, allowing a first pressure to be applied between the cleaning roller and the surface of the belt, and a second state in which a second pressure is applied between the cleaning roller and the surface of the belt. The second pressure is less than the first pressure.
