In a fixing device, when sheets of small width size are continuously passed and temperature rises in both side parts, a temperature control unit stops print control of an auxiliary lamp. When the temperature rise in both side parts continues after that, a drive control unit shifts the fixing device to a wait mode and pre-runs the fixing device. Moreover, in a low-temperature environment, when temperature rises in both side parts when sheets Ps of small width size are continuously passed, the temperature control unit switches temperature control of the fixing device to three-stage control. |
