Abstract

A layer of electrically photosensitive particles in an insulating light transparent material is sandwiched between and to a first electrode, and a transparent highly visulative film which is scanned by a corona discharge electrode with a high potential between it and the first electrode and subsequently scanned with opposite charge while the photosensitive surface is exposed to a light image.
