  • Patent number: 8145104
    Abstract: A metering skive for a developer roller which is adapted to shear and/or meter developer at a developer-skive interface while minimizing compression of the metered developer. The metering skive is adjustable to various shear angles and has a geometry which enables a portion of the developer flow to be sheared away toward a curved second surface of the metering skive while metering the developer flow in a manner which minimizes or reduces compression of the developer.
    Type: Grant
    Filed: December 19, 2008
    Date of Patent: March 27, 2012
    Assignee: Eastman Kodak Company

  • Patent number: 7577383
    Abstract: An apparatus and method for dispensing toner in an electrostatographic printer includes an apparatus for transporting powder into a developer station containing at least powder and magnetic carrier including a conveyance housing divided into a mixing space adjacent to a second separate transport space, the second transport space located adjacent to a development roller, a powder conveying device located in the conveyance housing comprising two or more augers and a conveyance controller for controlling the powder conveying device, including the one or more augers, such that the auger preferentially mixes in the first mixing space and transports in the second transport space as the powder conveying device conveys the powder toward the imaging device of a print engine.
