Electrostatographic printer and method

摘要

The printer (410) comprises a transfer member (494) which is driven along a continuous path and means (412) for depositing a toner image (416) in powder form on the transfer member (494). A substrate (428) is fed into contact with the transfer member (494), whereby the toner image (416) is transferred to the substrate (428). The toner image (416) on the transfer member (494) is heated in advance of the transfer and the transfer member (494) is cooled following the transfer to a temperature below the glass transition temperature Tg of the toner, prior to the deposition of further toner images on the transfer member (494). A pressure roller (432) is positioned in opposition to the transfer member (494) to form a transfer nip (426) therebetween, through which the substrate (428) passes, the substrate (428) wrapping partially around the pressure roller (432) both in advance of and following the transfer nip (426). The temperature of the pressure roller (432) is controlled to control the temperature of the substrate (428) as it passes through the nip (426). <IMAGE>
