PURPOSE:To achieve the prevention of going of toner to the back and the reduction of wasteful consumption of photosensitive paper by continuously disposing two kinds of chargers. CONSTITUTION:A first charger 6 having an opening part 5 for exposure and projection and an ordinary charger 7 are continuously disposed in opposition to the photosensitive paper 1 which is guided by guide rollers 3, 4 and is sent between fixing rollers 26, 27. An exposure means consisting of an image forming lens 20 and a lighting lamp 21 and the origianal 22 are disposed behind the first charger 6. Then, the photosensitive paper 1 is evenly charged by the simultaneous operation of the first, second chargers. after which the high voltage application to the first charger 6 is stopped by changing over of a high voltage switch 8. At the same time, the exposure means actuates to perform the instantaneous exposure of the original 22 through the opening part 5 for exposure and projection. Further the photosensitive paper 1 is conveyed as the fixing rollers 26, 27 revolve, thus the instantaneous is accomplished in succession. Hence, the electrostatic latent images are continuously formed on the photosensitive paper 1 and developing by a developing means 23 and fixing by the fixing rollers 26, 27 are accomplished, thus the intended object is achieved. |
