Calculation Of electrostatic potential in a electrophotographic development zone

Abstract

The electrostatic field in an electrophotographic development zone is calculated using a newly developed method. The zone is assumed to becomposed of four parallel layers, namely, a conductive substrate, a photoconductive layer, a development space, and a development electrode. For the calculation a charge pattern having a similar figure to a resolution test chart is considered on the surface of the photoconductive layer. The potential and the field distribution in the development space are calculated taking in consideration the effect of image charges needed to satisfy the boundary conditions. Various useful knowledge which cannot be clearlified by conventional methods is gained by the newly developed one.
