ELECTROPHOTOGRAPHIC IMAGING PROCESS AND APPARATUS

摘要

An imaging process utilizing a photoreceptor (13) comprising a conductive substrate, a photosensitive layer and an electrically insulating layer over the photosensitive layer wherein said photoreceptor is charged by means of an AC corotron so as to (17) provide an electrical field across the photosensitive layer only. The AC corotron drives the voltage across the electrically insulating layer to zero by means of a bias voltage (21) applied to the corotron shield.
