Abstract

PURPOSE:To eliminate the need for any even exposure part by letting the even exposure part serve also as an electric charging part as well as to perform copying at a high speed by performing even exposure at the backward moving of original scanning. CONSTITUTION:This is the device which is let to serve both as devices for performing charging and even exposure as pretreatment process prior to execution of ordinary copying process by using a photoreceptor 1 of two layer structure using CdS as its photoconductive layer, wherein a reflecting plate 20 for performing even exposure in the preprocess is provided between an original platen 14 and an original lighting device 4, and at the original scanning (exposure) by the lighting device 4, the reflecting plate 20 goes out from the exposure scanning surface and at the backward moving (other than original scanning) of the lighting device 4, the light from the lighting device 4 is reflected by the reflecting plate 20, whereby the even exposure is done to the photoreceptor 1. Since this permits the even exposure in the period required for applying the preprocess treatment at the backward moving other than the original scanning of the lighting device 4, the copying may be done at a high speed and the images free from any density change may be obtained.
