ABSTRACT:
A system for "capturing" charge within the structure of an electrophotographic imaging member in the imagewise exposed areas and thereby creating an electrostatic latent image in the imagewise exposed areas which in preferred embodiments of discrete non-touching particles of electrically photosensitive material stands up better against time, heat and light. Said imaging member is comprised of an insulating layer and electrically porous, mechanically discontinuous electrically photosensitive layer contacting said insulating layer. The process includes (1) charging, (2) imagewise exposure, and (3) promoting the dissipation of charge from the areas which are relatively nonexposed compared to the exposed areas, leaving behind an electrostatic latent image in the imagewise exposed areas. The electrostatic image thus created may be used or developed by any suitable technique other than by causing imagewise migration of said electrically photosensitive material.
