ABSTRACT:
A slit exposure type electrostatic copying apparatus having a photoreceptor surface wound on a rotatory drum movable along a path relative to a plurality of actuable processing stations disposed along the path and wherein the circumference of the photoreceptor drum is made slightly longer than the length of the maximum sized original with the diameter of the drum minimized to such an extent as to be sufficient to perform efficient copying. The machine is equipped with an automatic copy paper feeding mechanism from a roll of paper which can be switched over to a manual insertion by a simple operation, and is also provided with a supplementary light source so as to erase unnecessary charge on the non-latent image formed portion of the photoreceptor surface for better performance and prolonged life of the photoreceptor.
