Abstract

PURPOSE: To make copying speed several times higher by forming the same latent images on plural image carrier means through of one time exposure scanning thereby making plural copies.
CONSTITUTION: The original to be copied is placed on a moving original platen 1 and a dial is set at required sheet number, thence a print button is pushed. Then, the original platen 1 moves and the light from a lighting device 3 irradiates the original through a slit 2. This light is then led to the surface of the 1st photosensitive drum 8a and the 2nd photosensitive drum 8b by way of two sheets of mutually opposing the 1st mirrors 4a, 4b, lens 6, the 2nd mirrors 7a, 7b. The latent images are simultaneously formed on the photoreceptor surfaces having beforehand been evenly charged by chargers 9a, 9b and following to this, these latent images are turned to sensible images by developing devices 10a, 10b, thence they are moved to the transfer part.
