ABSTRACT:
An electromagnetic radiation sensitive copy medium and method for producing positive or negative copies electrostatically. In a first embodiment the copy medium includes a poled, radiation transmissive, pyroelectric insulative layer, an electrically conductive layer, and a photoconductive layer interposed between and electrically connected with the insulative and conductive layers. A second embodiment includes two insulative layers, a photoconductive layer that is interposed between the insulative layers, and an electrically conductive layer that is juxtaposed with one of the insulative layers. A third embodiment is basically similar to the first embodiment except that it includes a plurality of photoconductive layers, each being sensitive to a single, but different, color of light. The method disclosed for producing electrostatic copies with the above embodiments is also employable with prior art copy mediums that have ordinary insulative layers instead of the pyroelectric insulative layers of the present invention.
