Abstract
One or more toner images are transferred to an intermediate image member and then to a receiving sheet. The intermediate image member is made relatively conductive, for example, it has a resistivity less than 10.sup.9 ohm-cm facilitating transfer to the intermediate. To provide adequate allowance for variability for the impedance of receiving sheets a transfer backing roller forms a nip with the intermediate image member which transfer backing roller has a relatively low conductivity. For example, the transfer backing roller has a resistance of 10.sup.10 ohm-cm or greater.
