Abstract

A heating device includes a heater, a switching element connected between the heater and an AC power, and a controller performing a wave number control. A power control pattern includes a first pattern of which a control period is a first number, equal to or more than 2, of half waves and which satisfies a positive/negative symmetry, and a second pattern of which the control period is a second number, equal to or more than 2 and divisible by 4, of half waves and which satisfies the positive/negative symmetry. The controller sets the second pattern in a case where a supplying power duty is a first duty and sets the first pattern in a case where the supplying power duty is a second duty which is the supplying power duty larger or smaller by one step than the first duty, and performs wave number control.
