ABSTRACT:
A fixing device of this invention enables variable control of power to be supplied to a heat roller side or a press roller side in accordance with the temperature of the heat roller and the press roller while each mode is carried out. The heating range of a first induction heating coil on the heat roller side and the heating range of a first halogen lamp heater on the press roller side are set differently. In a copy mode, the temperature of the heat roller and the press roller is controlled in detail, and also controlled in accordance with the size of a sheet paper. In a copy standby mode, only the power required for maintaining a set temperature is supplied.
