<p>PURPOSE:To enable latent image formation, development, transfer and fixing without renewing of printing paper by using a disc-form photosensitive member which has the specified thickness and is mounted with photosensitive elements on its peripheral surface and a drum mounted with printing paper spirally. CONSTITUTION:Video signal 1' is modulated by a modulator 3 and a laser beam 3' is directly radiated to the circumferential surface of the disc-form photosensitive member 12 which has the specified thickness, mounted with photosensitive elements on its peripheral surface, whereby latent images are formed. The photosensitive member 12 revolves in the 12' direction, is charged with an even charger 13 and forms latent images when radiated with the laser beam 3'. The latent images are developed to toner images by a developing device 15 and the toner images are transferred onto the surface of printing paper 18 by the transfer charger 20 built in a drum 16 on which the paper 18 is spirally set. The paper 18 is wound and set, sheet by sheet, on the surface of the durm 16, revolves in the 16' direction, makes contact with the photosensitive elements and moves in the 16' direction. Thereby, the printing may be done without renewing of the printing paper.</p> |
