PROBLEM TO BE SOLVED: To provide a fixation device which is capable of suppressing creases generated when a toner image is fixed on a transferred sheet such as a print sheet, and preventing the increase in internal temperature and power consumption, and to provide an image forming apparatus including the fixation device.SOLUTION: A fixation device 16 includes a heating roller 71 having a main heater 75 and a sub heater 76 therein. The main heater 75 heats a central part 80c of a roller body 71A, and the sub heater 76 heats both end parts 80E of the roller body 71A. When fixation is performed on a thick sheet, a control part 8 controls the temperature so that the temperature of each end part 80E is lower than that of the central part 80C. When fixation is performed on a thin sheet, the control part 8 controls the temperature so that the temperature of each end part 80E is higher than that of the central part 80C. |
