Abstract

PURPOSE:To superpose two pictures through simple constitution by charging a photoreceptor, having a toner image, again, by projecting the other picture to form an electrostatic image, and then by developing it again. CONSTITUTION:Original P on transparent original table 8 is lightened up by lighting lamp 9 and scanned by scanning mirror 10 moving together with lamp 9 in a body, and its light is reflected by mirror 11 moving at a speed a half that of mirror 10, and at the position of simultaneous exposing-discharging device 3, positive charging is performed by primary charger 2 through the optical system of image forming lens 12, mirrors 13 and 14, etc., to form the image on photoreceptor 1. Through discharging by the AC corona discharge of discharger 3 and entire-surface exposure by entire-surface exposure lamp 15, an electrostatic image of the original picture with a high electrostatic contrast is formed on photoreceptor 1 of a drum, and toner is stuck to a normal picture part (dark part) by developing device 4 to obtain a visible image.
