ELECTROPHOTOGRAHPIC PHOTOSENSITIVE PLATE |
摘要 |
<p>ELECTROPHOTOGRAPHIC PHOTOSENSITIVE PLATE An electrophotographic photosensitive plate having, in order from the bottom up, an electrically conductive substrate, a photosensitizing layer composed of vitreous selenium and tellurium having a thickness of 0.1 to 3 microns, and a top organic layer including polyvinyl carbazole or a derivative thereof, the photosensitizing layer being composed of a first layer of 0.05 to 2 microns in thickness having 60 to 90 weight % of selenium and 40 to 10 weight % of tellurium and a second layer of 0.05 to 1 microns in thickness having a higher concentration of selenium than that of the first layer, and the second layer being positioned between the first layer and the top organic layer. This invention also provides a process of producing a latent electrostatic image on the plate by providing a negative electrostatic charge thereon and exposing the plate to a light image of visible light having a wavelength in the range of 4000 to 8000 .ANG.. Advantages of this electrophotographic plate are that it has high sensitivity to the visible light along with low residual potential.</p> |
