Abstract:
This invention provides a toner with improved charge and charge stability by suitable addition of extra particulate additives (EPA) such as aluminum cerium oxide and/or cerium zirconium oxide. The additives may be combined with toner in a conical mixer having selected temperature control. The invention also provides toner which may provide reduced print quality defects such as ghosting or residual image and fade-to-color.
