PROBLEM TO BE SOLVED: To provide a fixing device that can shorten a warming-up time, has a simple the structure (control) of a heat generating body and can efficiently uniformize temperature distribution in the axial direction of a heating roller. SOLUTION: Inside the hollow pipe type heating roller 10 with a heater 15 arranged inside, a high heat conductive roller 40 is arranged so that it may come into contact with the inner peripheral surface 17 of the roller 10 in the axial direction. The high heat conductive roller 40 is arranged near the downstream or near the upstream of a part 18 corresponding to the press contact position N with the pressure roller 20 in the rotating direction of the heating roller, and the heater 15 is arranged on the downstream side so as to be deviated from the rotational center of the heating roller.
