Abstract

The surface of a sheet-like member such as a sheet of paper may be illuminated by surrounding the member with confronted electrodes. Passing an AC voltage across the electrodes generates a corona discharge within the member. The light so produced facilitates the copying of images on the surface of the member by illuminating the surface from within.
