Abstract
An induction imaging process wherein the electrophotographic imaging member comprises at least three separate and distinct layers; namely, a conductive substrate, a photoconductive insulating layer and an insulating film overcoating the free surface of the photoconductive insulating layer. This process provides an efficient route for latent image formation, development and erasure of charge carriers trapped at the interface of the insulating overcoating and the layer contiguous with said coating. This process is especially suitable for use in combination with polar liquid development.
