ABSTRACT:
An electrostatic photographic copying apparatus comprising a frame member having a transparent plate on which to place an original to be copied, a rotatable photosensitive drum having an electrostatic photographic material on its periphery, an optical system for projecting an image of the original onto the surface of the photographic material, an image-forming zone disposed exteriorly of, and alongside, the periphery of said photo-sensitive drum for forming on said sensitive material an electrostatic latent image corresponding to the image of the original or a developed image corresponding to the latent image, a transfer zone for transforming said image to a transfer paper, and a transfer paper forwarding system for feeding the transfer paper on which the image has been transferred to a discharge end through a desired treating zone.
