摘要： While a recording sheet is passing through a fixing nip formed between a heating roller 41 having a heating layer and a pressing roller 42 pressed against the roller 41, a coil 43 is exited by high-frequency power from a power source and causes the layer to generate heat. An unfixed image on the recording sheet is fixed by the heat. The power source detects a zero cross timing of a rectified alternating current, detects an instantaneous value at a point a predetermined period after the zero cross timing, calculates an effective power of the alternating current based on the instantaneous value, and controls the output power to be a desired value determined based on the effective power and the surface temperature of the roller 41. Thus power input to the power source can be quickly detected and power output to the coil can be quickly and stably controlled.
