Abstract: PROBLEM TO BE SOLVED: To secure an optimum fixing state and to prevent offset by deciding what level is used out of plural heating temperature levels by concurrently using information on the number of carried members to be heated and information on temperature change between the members to be heated. SOLUTION: Output from a thermistor 5 provided on a heating body 3 so as to detect the temperature of the heating body 3 is A/D converted by an A/D convertion circuit, and fetched in a CPU after such operation. Then, a triac is controlled according to output from the CPU based on the information, and power to energize the heating body 3 is controlled by the phase and frequency control of AC voltage. In such a case, paper number control is performed in the case of selecting temperature control higher than a fixed level, and interpaper off control is performed in the case of selecting the temperature control lower than the fixed level. After setting the number of passing paper for all the temperature control and making the paper pass by the set number thereafter, the control is shifted to the interpaper off control.  In the case of judging that the temperature is insufficient, the temperature control is not changed, and in the case of judging that the temperature is high, the control is shifted to the next temperature control.
