  • Image forming apparatus component with triboelectric properties
    Patent number: 8038591
    Abstract: The present disclosure relates to an image forming device component that includes an elastomeric material having a surface and a triboelectric charging material that may be exposed on the elastomeric material surface. The triboelectric material may be exposed by a finishing process that results in removal of a portion of the material leaving voids in the surface. The surface may have a surface roughness in the range of about 0.1 to 5.0 Ra. The component may include a developer roller in an electrophotograhic printer and may provide contact electrification to a given toner during a printing operation.
    Type: Grant

  • Apparatus and method for transfer of image forming substances
    Patent number: 7702267
    Abstract: The present invention relates to a device or method which may reduce starvation in the transfer of an image forming substance to a developing location within an image forming apparatus. The device may include a first roller having a surface which is capable of supplying an image forming substance to a developing location. A second roller may then be included having a surface in rotating contact with the first roller. The second roller is capable of supplying image forming substance to the first roller. The second roller may comprise foam having a specified porosity, electrical conductivity, and/or be configured to rotate in a desired direction and/or desired speed relative to the first roller.
