Abstract
An electrical charging system for repeatedly electrically charging a photoconductor layer on an electrical conductor through charging that photoconductor layer, selectively discharging it, providing toner on the layer, and removing the charge image in the photoconductor for each of as many toners as desired for forming a final printed image, followed by using a removal radiation of a shorter wavelength on the photoconductor to avoid long term changes in the photoconductor. A further charging cycle may be used before the next printed image operation begins.
