  • Patent number: 6052551
    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.
