Abstract
The invention is an electrostatographic printer and a method of printing with such a printer. The printer includes a transfer member that is driven along a continuous path, and a toner image depositor that deposits a toner image in powder form on the transfer member. A substrate is fed into contact with the transfer member, and the toner image on the transfer member is heated in advance of the transfer; the transfer member is cooled following the image transfer to a temperature below the glass transition temperature T.sub.g of the toner; then further toner images may be deposited on the transfer member. A controlling pressure roller is positioned in opposition to the transfer member to form a transfer nip, through which the substrate passes, the substrate wrapping partially around the pressure roller both in advance of and following the transfer nip. The temperature of the controlling pressure roller can be governed to control the temperature of the substrate as it passes through the nip, thus attaining improved image transfer.
