CARRIER PARTICLE FOR ELECTROSTATOGRAPHIC DEVELOPER COATED WITH A BLEND OF A HALOGENATED POLYMER AND AN ACRYLIC POLYMER

摘要

POLYBLEND COATED CARRIER MATERIALS Electrostatographic developer mixtures comprising finely-divided toner particles electrostatically clinging to the surface of carrier particles comprising a core having an outer coating thereon comprising a polyblend of a first polymer possessing negative triboelectric charging chracteristics with respect to toner particles and a second polymer which possesses strong adhesive properties with respect to said core. The coated carrier particles have negative triboelectric charging properties and are particularly useful in development of negatively charged photoreceptors. Imaging processes are also disclosed.
