Abstract
A toner image is transferred from an image member to a receiving sheet using a backing member or corona charger to which a constant current source is applied for creation of a transfer electrical field. A logic and control receives an input indicative of the width of the receiving sheet and adjusts the current applied by the constant current source accordingly. Preferably, the logic and control also has an input indicative of the resistance of the receiving sheet, for example, determined by determining relative humidity and/or the thickness of the receiving sheet, which also is used with the width input to adjust the current applied by the constant current source.
