PROBLEM TO BE SOLVED: To provide a fixing device which is excellent in heat resistance and durability and can form a fixed image of high accuracy without occurrence of problems, such as an image defect, peeling defect of a paper sheet and the like arising by accompanying the flaw or deterioration of a fixing roller surface due to sliding of a heating roller and the fixing roller. SOLUTION: The fixing device is equipped with a fixing member 51 which is so supported as to allow its external perimeter to circulate, a heating means 53 which heats the fixing member 51 by abutting on its external perimeter, and a pressurization means 52 which circulates in pressurized contact with the external perimeter of the fixing member 51. The device conveys a recording material P carrying an unfixed toner image T in a pressure-contact part (fixing nip part) of the fixing member 51 and the pressurized means 52, and fixes the toner T by thermally fusing the same to the recording material P. The fixing device has a cleaning means 54 for performing cleaning on the surface of the fixing member 51. The cleaning means 54 is disposed on the upstream side of the heating means 53 with respect to the rotation direction of the fixing member 51. COPYRIGHT: (C)2006,JPO&NCIPI
