<p>Apparatus for the reproduction of visual images which uses a layer of photovoltaic material deposited on a substrate in such a way as to substantially increase the voltage produced when exposed to light according the pattern of an image to be reproduced so that no external charging voltage is required. The application of a toner to the material develops the image which may then be transferred to a copy sheet to reproduce the image. After discharge, either naturally by the passage of time or intentionally, the material may be exposed once again to permit the reproduction of a new image.</p> |
