Abstract

A fixing unit (31) fixes a toner image transferred onto a recording sheet. A plurality of cleaning units (7) is provided for a plurality of areas on an outer surface of the fixing unit (31) divided in a direction perpendicular to a rotating axis, respectively, and independently removes unwanted substances adhered to the fixing unit (31) by making contact with the fixing unit (31). An image-data-amount calculating unit (5, 520) divides a recording sheet into a plurality of sections, and calculates image data amount of the toner image transferred onto the recording sheet for each of the sections. A drive control unit (6) brings a cleaning unit (7) corresponding to an area of the fixing unit (31) used to fix the toner image into contact with the fixing unit (31) based on the image data amount calculated by the image-data-amount calculating unit (5).
