摘要:
A belt cleaning device (66) includes a cleaning roller (67a), a backup roller (68a), and a roller-pressing-state setting mechanism. The cleaning roller (67a) is disposed in confrontation with a surface of a belt (61). The backup roller (68a) is disposed in confrontation with the cleaning roller (67a) with the belt (61) interposed between the cleaning roller (67a) and the backup roller (68a). The roller-pressing-state setting mechanism selectively sets a state of the backup roller (68a) to a first state in which the backup roller (68a) is pressed against the cleaning roller (67a) via the belt (61), allowing a first pressure to be applied between the cleaning roller (67a) and the surface of the belt (61), and a second state in which a second pressure is applied between the cleaning roller (67a) and the surface of the belt (61). The second pressure is less than the first pressure.
