Claim:
1. A heater control device, comprising: 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; a data holding portion configured to store an attribute value indicating a variance of a resistivity value of the heater in advance; 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, wherein said power factor correction circuit includes a boost circuit configured to boost the alternate current voltage so that the boost circuit outputs the direct current voltage greater than the alternate current voltage, said inverter is configured to correct the specific alternate current voltage according to a resistivity value of the heater, said inverter includes a switching portion configured to switch the direct current voltage converted with the power factor correction circuit, and an inverter control portion configured to control the switching portion, and said inverter control portion is configured to change a switching state of the switching portion according to the attribution value of the heater determined in advance.
