Abstract

PURPOSE:To form margin parts at the leading ends of toner images by providing a reflecting plate and giving even radiation light to photoreceptor by as much as the width corresponding to the leading ends in place of exposing the leading ends of the original to the photoreceptor. CONSTITUTION:A stationary reflecting plate 23 is disposed below an original platen 13 in the position on the original scanning start side. The optical axis X of the scanning projection optical system first scans the bottom surface of the reflecting plate 23 before it scans the original O. Hence, this reflecting mirror 23 is started of scanning earlier than the original O to diffuse and reflect the incident light and projects white images to a photoreceptor 1' through a mirror 14, etc. The original images are then projected in continuation to the scanning terminal end Q of the reflecting plate 23. Hence, the fine width portions of the leading end parts O1, O2 of the original are not projected to the photoreceptor 1'. In this way, the leading ends of the original O are not exposed to the photoreceptor and in place the radiation light is applied by as much as the width corresponding thereto and therefore margin parts may be formed at the leading ends of the toner images.
