摘要：
The present application is directed to methods and devices for controlling charge buildup on a toner image as the toner image passes through one or more transfer nips. Charge buildup may be reduced by laterally offsetting a transfer roller from a photoconductor drum. The transfer roller may be constructed of an essentially non-compressible conductive material. AC current may be used to generate an electrical field between the photoconductor drum and the transfer roller.
