Abstract
A single-pass, multi-color electrostatographic printer has a transfer member which is driven along a continuous path. Toner images of different colors are simultaneously electrostatically deposited in powder form in register with each other on the transfer member to form a multiple toner image. The substrate is fed into contact with the transfer member for transfer of the multiple toner image to at least one face of the substrate. The printer includes a heater for the multiple toner image on the transfer member in advance of the transfer of the image to the substrate, and cooling capability for the transfer member following the transfer of the multiple toner image to the substrate, to a temperature below the glass transition temperature T.sub.g of the toner, prior to deposition of further toner images on the transfer member.
