In an electrostatographic copier in which imaging material is transferred from an image support surface to an overlying copy sheet in a transfer station, by electrical transfer charges, the variable leakage conduction of these transfer charges by the copy sheet away from the transfer area (to contacting conductive members) changes the available transfer field strength, thus affecting transfer efficiency and quality. Here the conductive members contacting the copy sheet while it is in the transfer station are electrically isolated from ground and connected to feed back the sheet leakage currents to circuitry providing a compensatory change in the applied transfer charges.
