Abstract
A fixing device includes a first heater, a second heater having a heat distribution different from that of the first heater, a heating member heated by the first and second heaters, and a temperature detecting element for detecting the temperature of the heating member. A power supply control element controls the power supply to the first heater and second heater in such a manner that the temperature detected by the temperature detecting element is maintained at a target temperature. After a fixing operation and until the temperature detected by the temperature detecting element rises from the fixing temperature to a stand-by temperature higher than the fixing temperature, the power supply element is adapted to effect power supply control different from that in the stand-by state.
