Zusammenfassung:A method for providing a developer mix having tribocharge uniformity across varying temperature and humidity conditions is provided. A developer mix used in a dual component development (DCD) system typically is a mixture of toner particles and magnetic carrier particles. Tribocharge uniformity is achieved in the developer mix by performing the step of treating the surface of the magnetic carrier particles with surface additives before the magnetic carrier particles are mixed with the toner particles. Surface additives include but are not limited to silica, titania and alumina.
