Abstract
PURPOSE:To prevent a film from being damaged caused by a wrinkle, etc., and the surface of a pressurizing roller from being melted by changing a set temperature according to the detected temperature of a temperature detecting member. CONSTITUTION:It is discriminated whether the temperature of a heater before energization is started is higher than a prescribed temperature, for instance, 100 deg.C or not. When it is low, the set temperature is set at 200 deg.C, for instance, and when it is high, the set temperature is set at 185 deg.C, for instance. A heat generating layer 16 is energized so that the temperature detected by a thermistor 17 reaches a first set temperature. When the temperature of the heater is higher than a second prescribed one, for instance, 60 deg.C, the energization to the heat generating layer 16 is started, and simultaneously, a main motor is driven. When it is lower than 60 deg.C, the energization to the heat generating layer 16 is started, and then, the main motor is driven after a prescribed time lapses. Thus, the set temperature is switched by the temperature of the heater before the energization is carried out when the formation of an image is started, so that sufficient fixing properties are obtained, and adverse influence caused by the rising of the temperature is prevented. Thus, the damage of a fixing film and a pressurizing roller is prevented.
