    • An apparatus and a method for controlling high voltage power of an image forming device are provided to minimize the number of transformers and rectifiers to reduce the size of the image forming device, thereby reducing product unit cost through the simplication. A direct current power supply controller(200) converts the first PWM(Pulse Width Modulation) signal provided from an engine controller to a switching waveform signal and outputs the switching waveform signal to a primary side of the first transforming unit(202). The first transforming unit transforms the switching waveform signal according to winding ratio and outputs the transformed output power to a rectifying unit(204). The rectifying unit rectifies the output power transformed in the first transforming unit and outputs rectified direct power respectively to the first and fourth direct current supplying units(206,208,210,212). The first and fourth direct current supplying units adjust direct current power rectified in the rectifying unit to a predetermined level and output the adjusted direct current power to the secondary side of the second and fifth transforming units.
