Abstract

Apparatus for providing structure in the charge distri-bution of a photoreceptor in electrostatographic repro-duction machines. The apparatus is comprised of a source of radiation 22, a plurality of apertures 28 and a lens system 24, 29 for focusing the radiation transmitted by the apertures onto a charged photoreceptor 11. The posi-tion of the apparatus relative to the photoreceptor can provide a method for control of the structure of the photo-receptor charge. The photoreceptor charge structure can be further controlled by providing preselected patterns for radiation transmitted by the apertures. The charge distribution of the photoreceptor can be structured to form a line or a dot pattern 15.
