Abstract: In a copying processing performed several times from the depression of a copy button of a copying machine until the surface potential of the photoreceptor drum is stabilized, a voltage sufficiently high for correcting the rise characteristic of the photosensitive layer on the drum surface is applied to a charger. A main circuit having a controlling portion to realize this corrects the output voltage of the high-voltage generating circuit which applies a high voltage to the charger to a voltage value necessary for the drum surface to be charged at a stable potential level. The main circuit charges the drum surface at the stable potential level necessary for development from copying of the first sheet.

Abstract: An electrographic copying machine has a photoreceptor drum which moves so that a photosensitive layer on its surface is successively charged, exposed, developed and charge-removed. The photosensitive layer is made of an amorphous material. The drum surface is charged by a charger before a latent image is formed thereon through exposure. A voltage generator is provided which supplies the charger with a voltage to charge the drum surface. It takes time for the potential of the charged drum surface at the developing section to reach a predetermined potential from a potential higher than the predetermined potential due to a rise characteristic of the surface potential. A controller is provided which corrects an output voltage value of the voltage generator to a voltage value necessary for the drum surface to be charged at the predetermined potential in a predetermined number of charging operations performed until the surface potential reaches the predetermined potential.
