Abstract

PURPOSE:To prevent the defective condition of fixing from being generated, by providing a means which stops the heating of an electric heater for a prescribed time corresponding to the temperature of a heating means at the time of increasing the temperature of the heating means prior to a fixing operation, and varying the heating stopping temperature and heating stopping time of the electric heater corresponding to the level of a supply voltage. CONSTITUTION:The titled deice is constituted in such a way that the means to stop the heating of the electric heater 5 for the prescribed time corresponding to the temperature of the heating means 19 especially to reduce the overshoot of the heating means 19 when the temperature of the heating means 19 rises prior to the fixing operation is provided, and the heating stopping means which varies the heating stopping temperature and the heating stopping time of the electric heater 5 corresponding to the level of the supply voltage is provided. In such a way, 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 the fixing easy to be generated at the time of applying a low voltage from being generated.
