Toner formulations containing extra particulate additive

摘要

The present invention relates to the use of extra particulate additives in selected chemically processed toner compositions for use in an image forming apparatus. The extra particulate additive may have a controlled aspect ratio and be combined with the chemically processed toner. The chemically processed toner may provide toner particles having controlled diameters and rheological properties that may be combined with a release agent. The release agent may also be selected with respect to, e.g., concentration and/or mean domain size within the toner particles including considerations of coating chemistry and/or DSC melting behavior.
