Abstract
In a multi-color imaging apparatus, the voltage differential between developed and undeveloped areas of a charge retentive surface is reduced for precluding edge effect development. The developed areas correspond to charged areas on the photoreceptor while the undeveloped areas represent discharged or background areas on the photoreceptor. Development of the charged areas is followed by an erase step for reducing the voltage differential between the developed areas and the non-developed background areas prior to the next development step.
