Abstract: A carrier for a developer composition includes a steel core having a shape factor of 6 or more coated with a coating at a coating weight of from 0.1 to 3.0% by weight of a total core weight. The coating is most preferably polymethyl methacrylate. The steel core also preferably has an average particle diameter of 70 to 89 micrometers and a size distribution wherein 1.5% or less of a total number of carrier particles have a size less than 38 micrometers. The carrier is preferably used in conjunction with toner particles to form a developer for particular use in devices utilizing hybrid scavengeless development. Use of a carrier in such a developer in a hybrid scavengeless development apparatus enables images to be achieved with properties similar to that achieved in offset lithography.

Abstract: Carrier particles comprise a core and a polymer coating that comprises a mixture of polymethyl methacrlyate (PMMA) and melamine. The coating compositions comprise from about 60 to about 80 percent by weight of PMMA and from about 20 to about 40 percent by weight of melamine. The carriers may be combined with a toner to provide a developer suitable for use in an electrostatographic process. Carriers comprising the PMMA/melamine coatings exhibit increased triboelectric charging, a more conductive carrier, and also contribute to reducing toner cohesion.
