Abstract

PURPOSE:To prevent a copying paper from coiling to a roller without forming a toner image on the top part of the copy paper, by irradiating intensified light from an exposing lamp by a reflecting mirror to the corresponding part to the top part of the copying paper on a photoreceptor. CONSTITUTION:A top end part 12a of an original 12 is arranged at a prescribed position 41 in advance and is in correspondence with a top end part in front of a carrying direction of copy papers 4, 5. An exposed region corresponding with at least the largest shape of the papers 4, 5 which are exposable on a photoreceptor 21, is the remaining part except the top end part 12a of the original 12 which is irradiated by an exposing lamp 14 through a transparent plate 11 and at least a part of a reflecting mirror 42 disposed adjacent to an early exposing end part. The mirror 42 is fixed to a machine body 1 in a selected angle and integral with the transparent plate 11. The mirror 42 reflects the light of the lamp 14 and makes an intensified regularly reflecting light irradiate to an optical device 15 from a reflecting mirror 16.
