Abstract

PURPOSE:To improve a fixing function, by performing the pre-operation of a heating means prior to a fixing operation to reduce overshoot, and varying the condition of the pre-operation corresponding to the level of a supply voltage. CONSTITUTION:The pre-operation of the heating means is performed prior to the fixing operation to reduce the overshoot, and by varying the condition of the pre-operation corresponding to the level of the supply voltage, it is possible to reduce the overshoot easy to be generated at the time of applying a high voltage, and to prevent the defective condition of fixing easy to be generated at the time of applying a low voltage. Thereby, a power source 1 possible to take a wide range of voltage is employed as the power source 1, and the voltage is applied to an image forming device including a heating fixer 10. A voltage detection circuit 2 detects the supply voltage, and transmits a measured voltage detecting signal to a CPU3. An electric heater 5 provided to the heating fixer 10 is connected to the power source via a heater control circuit 4, and generates heat corresponding to the signal of the CPU3. Also, the surface temperature of a roller is detected by a temperature detector 7 provided to the heating roller 19 of the heating fixer 10, and a temperature detecting signal is sent to the CPU3.
