Abstract
A cleaning unit includes a pressing roller for pressing a web for removing ink adhering to a conveying surface of a resist roller that conveys a sheet on which the ink has been discharged, against the conveying surface. A cleaning liquid supply unit supplies a cleaning liquid to an unused portion of the web. A web drive mechanism supplies the unused portion of the web to the nip region between the pressing roller and the conveying surface. A controller supplies the unused portion to which the cleaning liquid has been supplied by the cleaning liquid supply unit to the nip region by using the web driving mechanism thereby removing the ink from the conveying surface, and subsequently supplies the unused portion to which the cleaning liquid has not been supplied to the nip region by the web driving mechanism thereby removing the cleaning liquid remaining on the conveying surface.
