摘要： An image forming apparatus includes a fixing device having a heater, a signal generator for generating a prescribed cyclic signal in conformity with a waveform of an AC power supply applied to the heater, and a controller for controlling power feed to the heater. The controller determines whether a cycle of the prescribed cyclic signal becomes shorter than a prescribed period or not. When the controller has determined that the cycle has become shorter than the prescribed period, the controller controls power feed to the heater under phase control and when the controller has determined that the cycle has not become shorter than the prescribed period, the controller controls power feed to the heater under zero crossing control.

摘要： An image forming device that uses only one temperature sensor to detect temperatures of the recording sheet and a rotation member for fixing, and can perform the temperature adjustment control carefully in detail during the image forming operation. The CPU 61 performs the temperature adjustment control 1 by executing the temperature adjustment program 64b (step S109), then executes the paper passing judgment program 64a to judge whether or not paper is passing (step S110). As far as it judges that no paper is passing (NO in step S110), the CPU 61 continues to perform the temperature adjustment control 1 by executing the temperature adjustment program 64b. When it judges that paper is passing (YES in step S110), the CPU 61 performs the temperature adjustment control (step S112).
