Abstract
Depending on an output impedance of a commercial AC power supply calculated by an output impedance calculating unit, a control unit controls the supply of power so that the current of a first waveform pattern, capable of supplying an amount of power to be supplied to a heat generating member determined based on temperature information and capable of supplying power such that a harmonic current value is suppressed to be smaller than a predetermined value, flows into the heat generating member, or the control unit controls the supply of power so that the current of a second waveform pattern, capable of supplying an amount of power to be supplied to the heat generating member based on the temperature information and capable of supplying power such that the value of a flicker Pst is suppressed to be smaller than a predetermined value, flows into the heat generating member.
