    摘要： An imaging system wherein an imaging member comprises a layer of a homeotropically aligned nematic liquid crystalline material which is optically uniaxial residing on a photoconductive insulating layer. When the liquid crystal layer is subjected to an electrostatic charge and the photoconductive insulating layer is exposed to an imagewise pattern of activating electromagnetic radiation, the liquid crystalline material is subjected in selective areas to an electrical field which has components both in the plane of the layer and normal to the plane of the layer thereby inducing optical biaxiality in those areas of the imaging material. In a preferred embodiment of the invention a layer of a suitable overcoating material is arranged over the liquid crystal layer.
