Constant current-type high-voltage power supply apparatus and method of controlling power output from the same

摘要

A constant current-type high-voltage power supply apparatus (100) which is used in an image forming apparatus includes a leakage current detection unit (140) that detects a leakage current leaked from at least one output terminal (170) of the constant current-type high-voltage power supply apparatus and outputs the detected leakage current, a direct current voltage output unit (150) 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 (160) that controls power output from the constant current-type high-voltage power supply apparatus according to the output DC voltage.
