Abstract
A heating unit is heated by supply of an alternate-current power. A heating control unit executes a phase control to supply the alternate-current power to the heating unit for an ON-width in at least a half-wave period of the alternate-current power. A storing unit stores therein parameters for calculating the ON width. The heating control unit calculates the ON width based on the parameters stored in the storing unit and executes the phase control using a calculated ON width.
