Abstract

Proposed is the use of two counter-rotating synchronous photoreceptors (PAX) followed by a metering roll to develop an image. The photoreceptors are charged and exposed so that, for example, a secondary P/R repels toner whereas a primary PAX attracts toner. Forming a development nip between two such photoreceptors can essentially double the electric fields available for moving the toner onto the image area and away fiom the nonimage areas on the primary P/R. This enables the use of higher Viscosity Carrier fluids and or large development gaps. The enhanced developability offered by this invention would also be useful for very high process speeds.
