ABSTRACT:
An apparatus for removing the edge raggedness and background toner level of, for example, tri-level images by reestablishing the images and cleaning fields of the first developed image with a closely spaced electrode. The toner is redistributed by electrical and/or mechanical forces which leads to the removal of edge raggedness and background toner before transfer of the tri-level images to a copy sheet.
