发明名称 FIXING DEVICE AND IMAGE FORMING DEVICE
摘要 PROBLEM TO BE SOLVED: To reduce consumption power during heating of a fixing belt, by suppressing large temperature changes in the fixing belt, in fixing temperature control of the fixing belt.SOLUTION: A fixing control portion 52 sets one power capacity selected from different power capacities obtained by one or a combination of two selected from first-third heater lamps 35-37 as a reference mode, and heats a fixing belt 33 in the reference mode when the fixing belt 33 becomes lower than target temperature, during thermal fixing action to a plurality of recording sheets. When the fixing belt 33 becomes higher than the target temperature, heating of the fixing belt 33 is stopped. While the heating of the fixing belt 33 is stopped, if the fixing belt 33 exceeds upper limit temperature by an overshoot, the reference mode is updated to power capacity which is smaller than the power capacity set last time.
