  • Publication number: 20070196151
    Abstract: The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member for producing an electrostatic latent image on a receiver, a development station for applying toner particles to said latent image which forms a developed toner image on the receiver. A fuser assembly is included for fixing the developed toner image, to form a fused toner image on the receiver. A transport member is provided for transporting the receiver to or from the fuser assembly, the transport member having a substrate bearing an oil-absorbing layer that includes transparent aluminum inorganic particles of pseudo-boehmite, dispersed in an organic binder, and a wax having a melting point less the 100° C.

  • Publication number: 20050214021
    Abstract: An electrophotographic machine includes a dielectric member configured for carrying a toner image. A transfer roller engages the dielectric member and transfers the toner image to an image substrate. A transfer roller power supply biases and periodically reverse biases the transfer roller. A transfer roller cleaning brush having conductive bristles engages the transfer roller. An electrically conductive brush housing encloses the transfer roller cleaning brush and defines an opening through which the bristles contact the transfer roller. The brush housing is electrically charged to the same electrical potential as said transfer roller and is selectively discharged.

  • Publication number: 20050214020
    Abstract: An electrophotographic machine includes a dielectric member carrying a toner image. A biased transfer roller engages the dielectric member and transfers the toner image to an image substrate. A cleaning brush having a plurality of bristles, at least some of which are electrically conductive, engages the transfer roller. An electrically conductive housing encloses the cleaning brush. The bristles contact the transfer roller through an opening in the housing. At least one of the cleaning brush and the housing is biased to substantially the same electrical potential as the transfer roller.
