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.

摘要： Disclosed is a method of forming a latent electrostatic image on a segment of an electrostatographic photosensitive device which comprises a grounded conductive substrate having a layer of photoconductive material on its surface which is in turn overcoated with an insulating organic resin. The method comprises:A. applying an initial electrostatic charge of one polarity to the surface of the photosensitive device,B. advancing the segment of the photosensitive device toward a corona emitting grid which is wider than the segment selected,C. activating the grid when the trailing edge of the segment reaches the lead edge of the grid to thereby apply an electronic field of either alternating current or direct current of polarity opposite that of the polarity of the initial charge,D. exposing the segment to imagewise activating radiation in the full frame flash exposure mode while continuing to apply the electronic field thereto;E. continuing the advancement of the segment past the corona emitting grid while continuing the application of the electronic field thereto until the lead edge of the segment reaches the rear edge of the grid and then deactivating the grid; andF. forming an imagewise potential distribution across the insulating layer by uniformly exposing the segment to activating radiation.
