A direct current-jump, nonmagnetic, monocomlponent electrophotographic development system

摘要

A new monocomponent electrophotographic development system is introduced, in which nonmagnetic toner jumps the gap between the development roller and the photoreceptor only under the influence of the direct current electric fields of the latent image. This development system requires for its operation low toner adhesion, which is achieved by a patented toner formulation. Such a development system is ideally suited for a small size, low cost, color electrophotographic engine. A prototype color printer utilizing this unique development system in an image-on-image architecture has been implemented to demonstrate its printing capabilities. Photomicrographs of print samples are shown and the scalability and extendibility of this technology are discussed. (C) 2006 Society for Imaging Science and Technology.
