Abstract
Carrier includes a mixture of carrier particles. The mixture may contain first carrier particles containing carrier cores that are coated with a polymer coating, the coating containing polymer and conductive particles, and second carrier particles containing carrier cores that are not coated with a polymer coating. The mixture may contain carrier particles having a conductivity of at least about 5×10−8 (ohm-cm)−1 and carrier particles having a conductivity of less than about 1×10−8 (ohm-cm)−1.
