Abstract

A photoelectrographic element for electrostatic imaging, containing a conductive layer and a photosensitive layer, is produced using photosensitive layer materials which form a barrier to charge injection where exposed to ultraviolet radiation. As a result, exposed areas can be charged, while unexposed portions cannot. The photosensitive layer contains an organic photoconductor, an ultraviolet radiation sensitizer, and, optionally, an organic binder. A method of forming images with this photoelectrographic element is also disclosed.
