  • Transfer device and system for an electrophotographic device comprising multiple electrodes
    Patent number: 9501001
    Abstract: A device for transferring images from an image donating member to an image receiving medium comprises a substrate, at least two electrodes disposed on the substrate, and at least one layer of coating disposed on the substrate having an outer surface for forming a nip region with the image donating member. The at least two electrodes are controllable to produce an electric field and control a position thereof at the nip region to allow transfer of an image from the image donating member to the image receiving medium in an image transfer operation.
    Type: Grant

  • Toner adder roll having an abrasive agent additive
    Patent number: 9261812
    Abstract: A toner adder roll according to one example embodiment includes an electrically conductive shaft defining an axis of rotation of the toner adder roll. A foam member is cylindrically disposed about the shaft and forms an outer circumferential surface of the toner adder roll. The foam member is composed of a polymeric open-cell foam material. An abrasive agent is dispersed on the outer circumferential surface of the toner adder roll.

  • Transfer NIP for an electrophotographic device, and methods of making and using same
    Patent number: 8588667
    Abstract: An imaging apparatus having a toner transfer station, including a donating member for donating toner forming an image; and a transfer roll which serves to form a transfer nip in which toner is transferred from the donating member to a media sheet disposed in the transfer nip between the donating member and the transfer roll, wherein a product of a resistivity of the transfer nip and a dielectric constant thereof is greater than or equal to a product of a resistivity of the media sheet and a dielectric constant thereof.
