Abstract
An electrophotographic recording apparatus comprises an electrophotosensitive member, and a corona discharge device located adjacent the electrophotosensitive surface thereof. The corona discharge device includes a discharge wire spaced from the electrophotosensitive surface, and a covering member for substantially covering the space between the discharge wire and the electrophotosensitive surface at each end of the discharge wire. In some embodiments the covering member spans the space between the discharge wire and the electrophotosensitive surface and contacts the electrophotosensitive surface.
