ABSTRACT:
An electrophotographic machine has a photoreceptive member supporting a composite color toner image formed of multiple layers of different colored toners. The composite toner image is pre-transfer charged at a first voltage level and recharge at a second voltage level less than the first voltage level. The background toner is preferentially charged by the second charging to reduce transfer of the background toner to the substrate.
