Abstract
A toner powder composition is provided wherein the toner particles are coated with a metal alkoxide. The product powder displays improved flow characteristics. The coating is accomplished by contacting starting toner particles with a solution of metal alkoxide in a solvent wherein the toner particles are substantially completely insoluble, followed by separation and drying. The metal of the alkoxide has a valence of 3 through 5, and the alkoxy groups contain not more than 10 carbon atoms.
