ABSTRACT:
A device in a liquid development system to prevent soiling of support rollers for an imaging member wherein the support rollers previously soiled the back surface of the imaging member. The invention comprises insulating the support rollers and applying a developing voltage only when the imaging member has been inserted between the support rollers and another set of rollers which also serve as development electrodes so that voltage is not applied on a given roller pair not carrying the imaging member, thus developer material is not induced to flow on roller pairs not bearing the imaging member.
