ABSTRACT:
In a photoconductive image processing system, consistent copy quality is possible if the charge necessary for the transfer of a toner image is produced by a source of substantially constant current. Changes in transfer material or humidity will not affect the current and thus the charge delivered. As a result, readjustment of the charge source is obviated.
