Patent ID: 8260167

Claim:
An image forming apparatus comprising: a charging unit uniformly charging a surface of a photoconductive drum; a light exposing unit performing light exposure on the surface of the photoconductive drum to form an electrostatic latent image; a developing unit developing the electrostatic latent image using a developer; a transferring unit transferring the developed electrostatic latent image onto a printing medium; a fusing unit fusing the transferred developed electrostatic latent image onto the printing medium; a cleaning unit removing the developer remaining on the photoconductive drum; and a high-voltage power supply supplying power to the charging unit, the light exposing unit, the developing unit, the transferring unit, the fusing unit, and the cleaning unit, wherein the high-voltage power supply comprises: a board having at least one bent portion separating a first region of the board from a second region of the board, the first region of the board not being coplanar with the second region of the board; a first circuit, on the first region of the board, generating a second voltage according to a first voltage; and a second circuit, on the second region of the board, amplifying the second voltage and then rectifying the amplified second voltage.
