Abstract
Full color, single pass and two-pass imaging processes using black, magenta, cyan and yellow toners and Non-interactive Development without fringe field development. Corona discharge is utilized for voltage leveling certain developed images prior to their passage through DAD developer housings. A Raster Output Scanner (ROS) used for creating the latent electrostatic images is also used for voltage leveling of images developed on the first pass of the two pass imaging process in order to remove certain other images for eliminating fringe field images as well as other undesired images.
