Abstract

Disclosed is a method for the cyclic electrostatic imaging of a photoreceptor consisting of a photoconductive layer and an insulating overcoating. The method consists of the following three steps: 1. Simultaneously exposing the photoreceptor to the optical image to be recorded, and electronically charging it with a positively bided AC corotron,

Disclosed is a method for the cyclic electrostatic imaging of a photoreceptor consisting of a photoconductive layer and an insulating overcoating. The method consists of the following three steps:

1. Simultaneously exposing the photoreceptor to the optical image to be recorded, and electronically charging it with a positively bided AC corotron,

2. Uniformly exposing the photoreceptor, and

3. Simultaneously erasing the electrostatic image on the photoreceptor and uniformly charging the overcoating to a positive potential.

The process makes use of a positively biased AC corotron whi& may use, for example, a bias of +lo00 volts DC at 60Hz. This corona device performs two operations simultaneously; i.e., the erasure of imagewise potential distributions on the photoreceptor, and uniformly charges the overcoating to the desired positive potential. The process offers the additional advantage of eliminating discharging steps which characterize other processes for the cycling of overcoated photo- receptors.
