PHOTOSENSITIVE BODY FOR ELECTRONIC PHOTOGRAPHY

摘要

PURPOSE:To obtain a good picture having very little fog of highlight even when making many copies by providing a PVK layer on a photosensitive body made by laminating a photoconductive layer and an insulating layer successively on a supporting electrode. CONSTITUTION:A photosensitive body used in a copying system that obtains many copies repeatedly by image forming process including optical image exposure simultaneous electrostatic charge are piled in the order of a photoconductive layer 2, an insulating layer 3 and a PVK layer 4 on a supporting electrode 1. The film thickness of the TVK layer is 0.05-1.0mum. The PVK layer 4 provided as a surface layer arrests injection of charge from a transfer roller or a transfer corona charger to which high voltage is applied when transferring. By this way, many copies can be obtained from the same electrostatic latent image without influenced by fog of highlight part.
