  • Electrophotographic Roller with Resistance to Nip Banding
    Publication number: 20130243500
    Abstract: An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.
    Type: Application

  • Process for providing improved electrical properties on a roll for use in electrophotography
    Patent number: 8171638
    Abstract: A method and system for producing rolls for electrophotography are provided. The rolls can be rotated and shifted laterally during an oxidative baking process to produce finished rolls having improved electrical and printing characteristics. The oxidation of the rolls may be controlled to provide a corresponding increase in surface electrical resistance to within plus or minus 25 microns of a selected roll thickness.
