Abstract
A heater control device includes a power factor correction circuit configured to convert an alternate current voltage from a commercial power source to a direct current voltage; an inverter configured to generate a specific alternate current voltage from the direct current voltage converted with the power factor correction circuit; a heater configured to receive the specific alternate current voltage generated with the inverter; and an excessive temperature rise preventing portion configured to interrupt the specific alternate current voltage generated with the inverter from being supplied to the heater.
