ABSTRACT:
A bias transfer member including an internal heating element is disclosed. The transfer member includes a thermocouple or voltage activated switch for allowing current flow through the heating element in response to predetermined conditions to raise the temperature of the transfer member and thereby decrease and maintain a substantially constant resistivity in the transfer member so as to extend the electrical life of the transfer member.
