Abstract
Disclosed is a process for generating consistent high quality images comprised of (1) providing a xerographic imaging or printing apparatus; (2) adding thereto a stable two component developer composition comprised of toner composition with an average particle diameter of from about 6 to about 10 microns with resin particles, first pigment particles, second magnetite pigment particles, which are present in a greater amount than the first pigment particles, and blended flow additive particles; and carrier particles consisting of a ferrite core, or a steel core, and a coating thereover selected from the group consisting of terpolymers of styrene, methacrylate, and triethoxysilane; and polymethacrylate, which coating has incorporated therein conductive particles; (3) forming electrostatic latent images or magnetic images in the apparatus; and (4) developing the images formed.
