Abstract
An image forming apparatus includes a power supply voltage detector, a power supply cycle detector, a voltage converter, and a controller. The power supply voltage detector detects a power supply voltage value of a commercial alternating-current voltage. The power supply cycle detector detects a power supply cycle of the commercial alternating-current voltage. The voltage converter performs switching of the commercial alternating-current voltage, and thereby converts the commercial alternating-current voltage into a heater alternating-current voltage to be applied to a heater. The controller controls the voltage converter and thereby generates the heater alternating-current voltage, on a basis of the power supply voltage value detected by the power supply voltage detector and the power supply cycle detected by the power supply cycle detector. The heater alternating-current voltage has an effective value that is stepped down from an effective value of the commercial alternating-current voltage, and is synchronized with the power supply cycle.
