    Abstract: Electrodes are embedded in a biased transfer roller for the transfer of a xerographic image. The electrodes, which run the length of the roller, are deposited on an insulating core surrounding the shaft. A conformable semi-conductive layer of a flexible elastomer covers the embedded electrodes. The semi-conductive layer limits current flow between embedded electrodes, relaxes charge deposited on the roller surface, and maximizes the electric field that attracts the toner from the photoconductor to the image receiving surface (substrate or intermediate). The electroded biased transfer roller may tailor the electric fields within the nip, pre-nip, and post-nip regions between the photoreceptor and the image receiving surface of the xerographic 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.
