摘要： Disclosed is a method for forming a latent electrostatic image on a photosensitive device comprising a grounded conductive substrate having on its surface a layer of photoconductive material which is in turn overcoated with a layer of insulating organic resin. The method involves applying an initial electrostatic charge of one polarity to the surface of the photosensitive device followed by the steps of:1. applying to the surface of the photosensitive device an electronic field of direct current having a polarity opposite to that of the initial electrostatic charge, and, either simultaneously or sequentially, exposing the device to imagewise activating radiation;2. uniformly exposing the device to activating radiation; and3. applying an electrostatic charge of the same polarity as that of the initial charge to the surface of the photosensitive device to thereby simultaneously erase the electrostatic charge from the device and initially charge it as the first step in the next cycle.
