Abstract: PURPOSE:To provide the device which is long in maintenance period, averts an increase in the size of the device and maintains the initial cleaning capacity without degradation by densely winding a cleaning member on at least un-winding side from the center. CONSTITUTION:Since a cleaning web 21 is pressed via a pressing roller 22 to a fixing roller 11, offset toners are successively cleaned by the rotation of the roller 11 and the web 21 which is stuck with the toners and is degraded in performance is successively taken up on the used roll 21b side. The fresh web 21 is successively let off by the unused roll 21a. Meanwhile, the un-winding roller is not mounted to the roll 21a of the web 21 and the web 21 is wound in the tight state having no spaces. The web which cannot be wound for just 15m if the un-winding roller is used can be wound for about 19m in the case of the roll 21a of, for example, 35mm outside diameter. The maintenance period is thus prolonged from the processing time of 150000 sheets of transfer paper up to the processing time of 190000 sheets and the cost is reduced. In addition, the size of the device is reduced.
