Title: Image forming device
Inventor: IMAGAWA SHINJI
IPC: G03G15/02
Filed: 1991-10-04
Abstract: PURPOSE:To provide an image forming device capable of forming the image of an original on a sheet by means of the simple constitution. CONSTITUTION:An electrification roller serving also as a transfer roller and an electrification power source are connected by an electrification/transfer/ voltage switching device and an electrification voltage of negative potential is applied to the roller, thereby electrifying the surface of a photosensitive drum to the negative (ST1). The surface of the photosensitive drum electrified to the netagive potential is irradiated with light led from a light source via plural mirrors and reflected from the original, thereby forming an electrostatic latent image on the surface of the photosensitive drum (ST2). A toner image is formed on the surface of the photosensitive drum by a developing tank (ST3). When the photosensitive drum makes a second rotation, the roller and a transfer power source are connected by the electrification/transfer switching device and a transfer voltage of positive potential is applied to the roller (ST4). The toner image formed on the surface of the photosensitive drum is transferred on the sheet (ST5).
