Printing machine and method using a bias transfer roller including at least one temperature-maintaining device

Abstract

A printing apparatus includes a transfuse member, an intermediate transfer member and a transfer member assembly having a transfer member that electrostatically transfers a toner image from the intermediate transfer member to the transfuse member. The transfer member includes at least one temperature control device that maintains the transfer member within a predefined range. A controller assembly may be connected to the at least one temperature control device for extending the electrical life of the transfer member assembly by maintaining the transfer member at a substantially constant resistivity.
