  • Publication number: 20070237547
    Abstract: According to various embodiments, the present teachings include electrophotographic charging devices and methods for charging a receptor with a solid state charging device. In an exemplary embodiment, the solid state charging device can include a dielectric layer, a first electrode disposed adjacent to a first surface of the dielectric layer, and a second electrode, wherein the second electrode has a first surface disposed adjacent to a second surface of the dielectric layer. The solid state charging device can further include a plurality of nanostructures, wherein each of the plurality of nanostructures has an end in electrical contact with a second surface of the second electrode. The exemplary solid state charging devices including the nanostructures can use less voltage than conventional charging devices, produce a reduced amount of oxidizing agents, such as, ozone and NOx, and/or operate at a lower temperature.

  • Publication number: 20070019988
    Abstract: The presently disclosed embodiments are directed to release fluids or agents that are useful in release coating in toner-based technologies. More particularly, the embodiments pertain to the addition of metal chelating agents to release fluids to prevent byproduct reactions from the fusing process that would otherwise decrease fuser member life and image quality.

  • Publication number: 20060013617
    Abstract: In a xerographic printing apparatus, a scorotron places a uniform charge on a photoreceptor for forming electrostatic latent images. Two conductive pin arrays are disposed in a housing defined by sidewalls and a grid adjacent the photoreceptor. For each array, the distance to the adjacent sidewall is 1.0 to 1.5 the distance to the grid.
