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