Abstract: A transfer member for a printing device includes a shaft, a rigid cylindrical core member, mounted on the shaft, an outer layer supported on the rigid cylindrical core member, and optionally a conformable intermediate layer, spacing the cylindrical core member from the outer layer. The outer layer defines an outer surface of the transfer member, and is configured for receiving a toner image thereon. The cylindrical core and outer layer have a same axis of rotation as the shaft. The rigid cylindrical core and/or the conformable intermediate layer, where present may be electrically biased, relative to a photoconductor drum of the printing device.

Abstract: A development system includes a housing configured for accommodating a developer material which includes toner particles. At least one magnetic roller is positioned within the housing to attract the developer material to a surface of the magnetic roller(s). A continuous developer belt is positioned to attract the toner particles from the at least one magnetic roller to a surface of the developer belt. The developer belt is carried on a plurality of developer rollers. One of the developer rollers is positioned adjacent to an image transfer member, such as a belt or drum, with a photoconductive surface. Some of the toner particles are transferred to a latent image formed on the image transfer member to generate a toner image layer, which is applied to a sheet of print medium.
