Image forming apparatus
An image forming apparatus includes a heat source of a fixing device to heat when an alternate current signal is supplied thereto; a conduction control circuit for controlling an alternate current power source with a conduction control signal, and for supplying the alternate current signal to the heat source; and a control unit for outputting the conduction control signal in a specific pattern. The conduction control circuit includes a conduction control element for switching between conduction and non-conduction at a zero cross timing of the alternate current power source according to the conduction control signal, and for supplying the alternate current signal.
