ABSTRACT:
A fixing apparatus that fuses and firmly adheres an unfixed developer onto a recording medium includes a heating roller and a pressure roller; a belt-shaped cleaning member that is disposed so as to abut on the heating roller and cleans the surface of the heating roller, the cleaning member being impregnated with oil in advance; a feed roller that sends out the cleaning member; a wind-up roller that winds up the cleaning member having cleaned the heating roller; a press-contact roller disposed so as to press the cleaning member against the heating roller on which the cleaning member abuts; and an oil absorbing layer that is disposed on an outer circumferential surface of the press-contact roller and absorbs oil exudation out of the cleaning member.
