Abstract

Polymer-coated, electrostatographic carrier particles having stable, constant triboelectric charging properties when mixed with primary-color toner materials may be provided by the addition of binary and ternary pigment mixtures to the coating composition. In addition, toner blends of different colored toners may be provided with a common developability rate characteristic by incorporating thereto fine-size particles of silica, zinc oxide, clay and kaolin.
