    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.

    摘要翻译： 带清洁装置（66）包括清洁辊（67A），一个支撑辊（68A），和辊压状态设定机构。 清洁辊（67A）设置在对抗用皮带（61）的表面上。 支承辊（68A）与所述清洁辊（67A）与所述清洁辊（67A）和支承辊（68A）之间的皮带（61）对抗设置。 所述辊压状态设定机构选择性地设定支承辊（68A）的状态，其中支承辊（68A）经由允许第一带（61）压靠于清洁辊（67A）的第一状态 清洁辊（67A）和带（61）的表面上，并且其中的第二压力被清洁辊（67A）和带（61）的表面之间施加第二状态之间被施加的压力。 所述第二压力小于所述第一压力。
