Abstract
A first high-voltage power supply includes a first transformer configured to generate a voltage to be supplied to a first wire of a charger, and a second high-voltage power supply includes a second transformer configured to generate a voltage to be supplied to a second wire of the charger. The first and second high-voltage power supplies respectively drive the first and second transformers in accordance with pulse signals that are supplied from a CPU and that have the same frequency and phase. The first and second high-voltage power supplies respectively supply, to the first and second wires of the charger, voltages generated by driving the first and second transformers.
