  • Method of removing impurities from a transport member during an electrostatic imaging process
    Patent number: 5521687
    Abstract: An imaging apparatus including a device for transferring a toner image from an image-forming medium to a receiving material including an endless movable intermediate provided with a top layer which, in a first transfer zone, is in contact with the image-forming medium, a heating device for heating the toner image on the top layer of the intermediate, a pressure applying device which, in a second transfer zone, can be brought into contact with the intermediate, a transport device for transporting the receiving material through the second transfer zone, and a cleaning device following the second transfer zone, between the second and first transfer zones, brought into contact with the top layer of the intermediate, the cleaning device being provided with an impurity-absorbent material on its outer surface.

  • Toner image transfer apparatus including intermediate transfer medium
    Patent number: 5361126
    Abstract: An imaging apparatus including a transferring device for transferring a toner image from an image-forming medium to a receiving material, comprising an endless movable intermediate provided with a top layer which in a first transfer zone is in contact with the image-forming medium, heater for heating the toner image on the top layer of the intermediate, a pressure applying roller which in a second transfer zone can be brought into contact with the intermediate, a transport roller for transporting the receiving material through the second transfer zone, wherein removal of impurities transferred by receiving materials to the top layer of the intermediate is realized by absorption of the impurities by an impurity-absorbent material within the intermediate.
