PROBLEM TO BE SOLVED: To provide an image formation device capable of realizing power control satisfying both a flicker standard and a harmonic current standard by a simple configuration.SOLUTION: A control unit for controlling power supply from a commercial AC power source to the heat generation element of a fixation unit on the basis of temperature information controls power supply so that, when the output impedance of the commercial AC power source calculated by an output impedance calculation unit is smaller than a prescribed value, the current of a first waveform pattern, in which the amount of electric power to be supplied to the heat generation element as determined on the basis of the temperature information is suppliable and power supply in which the value of a harmonic current is suppressed to a smaller value than a prescribed value is possible, flows to the heat generation element, and when the output impedance is greater than or equal to the prescribed value, the current of a second waveform pattern, in which the amount of electric power to be supplied to the heat generation element as determined on the basis of the temperature information is suppliable and power supply in which the value of a flicker Pst is suppressed to a smaller value than a prescribed value is possible, flows to the heat generation element. |
