PURPOSE:To reduce the cost of an image forming device and prevent the variance of electrification of a photosensitive surface and transfer toner images well by supplying power to an electrifier and a transfer device with a single high voltage power source and supplying a constant voltage to the electrifier and supplying a constant current to the transfer device. CONSTITUTION:A uniform electric charge is given to a photosensitive surface 1a of a photosensitive drum 1 by a corona discharging wire 2a of an electrifier 2 to which a high voltage is applied. When the photosensitive surface 1a reaches an exposure part, it is exposed, and an electrostatic latent image is formed on the photosensitive surface 1a. When the electrostatic latent image formed on the photosensitive surface 1a reaches a developing part, it is developed with a toner in a developing device 3 by the developing device 3 to form a toner image. This toner image is transferred to a transfer paper, which is carried to a transfer part, by the corona discharge of a corona discharging wire 4a of a transfer device 4 to which a high voltage is applied, and the transfer paper is carried in the direction of an arrow 12, and the toner image is fixed thermally by a fixing device, and the transfer paper is carried out from a machine. |
