In a fixing apparatus that an unfixed developer is fused and fixed by heating/pressurizing a recording medium on which an image of the unfixed developer is formed, a belt-shaped cleaning member is fed from a feeding roller, and the cleaning member is made to respectively contact a heating roller and a pressure roller by a pressure-contact roller, thereby cleaning that the heating roller and the pressure roller, respectively. When a winding roller takes up the cleaning member which has cleaned a roller surface, guide rollers are respectively provided between the pressure-contact roller and the winding roller, and between the feeding roller and the pressure-contact roller so as to contact the cleaning member.
