PURPOSE:To form two images by one stage of developing device and to miniaturize an image forming device by providing a developing device with a beltlike recording electrode and forming lumps of a developer. CONSTITUTION:A photosensitive film 11 is rotated as shown by an arrow and the magnet roller of the developing device 13 is rotated to convey toner 18 as shown by an arrow to form the lumps of toner in a development area; while a voltage is applied between the recording electrode 15 and a sleeve 13a, an LED array optical system 19 performs image exposure. A CGL 11c generates photocarriers and positive holes move in the CTL 11d nearby the surface of a photosensitive body to form latent image charges, thereby forming an electrostatically charged toner image 20 held at the electrostatic force of the latent image charges. Then the toner image is transferred to a transfer roller 22. The transferred toner image 24 is fixed on recording paper 21 by a fixing device 25 to obtain a semipermanent image. Remaining toner 27 on the photosensitive paper 11 after transfer is discharged electrostatically by using a destaticizing power source 28. |
