Abstract
A constant current-type high-voltage power supply apparatus which is used in an image forming apparatus includes a leakage current detection unit that detects a leakage current leaked from at least one output terminal of the constant current-type high-voltage power supply apparatus and outputs the detected leakage current, a direct current voltage output unit that outputs different direct current (DC) voltages according to whether the leakage current detected by the leakage current detection unit is input, and a power control unit that controls power supply to the constant current-type high-voltage power supply apparatus according to the output DC voltage.
