PROBLEM TO BE SOLVED: To obtain excellent operability even in the case of abopting a fixing unit of an on-demand type, and to appropriately execute the cleaning of a pressure roller. SOLUTION: A printer control device 26 starts the cleaning paper controlling when receiving a cleaning paper request command from an external device 28. When a recording paper leading end passes through a nip of the fixing unit, a ceramic heater 10a starts heating to control the temp. at 200 deg.C being higher than the control temp. (170 deg.C) at the normal printing time. As a result, the soiling toner stuck on a heating roller 10e is fused and stuck to the rear surface of the recording paper, so that a pressure roller 10e is subjected to cleaning. |
