ELECTROPHOTOGRAPHIC PRINTING SYSTEM ABSTRACT OF THE DISCLOSURE An apparatus for developing an image on a photoconductive surface. The apparatus includes a roller positioned adjacent to the photoconductive surface. Negatively charged toner is supplied to the surface of the first roller where the toner electrostatically adheres, either in a uniform layer or a variable layer, to the surface of the first roller. The negatively charged toner electrostatically adhered to the surface of the first roller is then transferred to the photoconductive surface. The apparatus may also include a second roller held at a positive charge relative to the first roller for electrostatically transferring toner from the second roller to the first roller. Alternately, the positive charge on the second roller relative to the first roller may be produced by placing a negative charge on the first roller or by placing a negative charge on the second roller and a more negative charge on the second roller. By placing a negative charge on the second roller, the toner will also be negatively charged before transfer to the first roller.
