US Patent 7286149 Direct xerography system

A system for printing is described. The system uses at least one cantilever, and more typically a plurality of cantilever to transfer charge, either to or from a dielectric surface. The resulting charge distribution represents an image. Toner deposited over the dielectric surface is attracted to the charged portions of the dielectric. Thus the toner also forms the image. The toner image is then transferred and affixed to a printing surface.
