More Information
Summary:A toner composition and a method of making a toner composition wherein toner particles having an average size in the range of 1-25 μm may be mixed with silica particles and alumina particles surface treated with an inorganic/organic compound. The silica particles may have a primary particle size in the range of 2 nm to 20 nm and may be present in the range of 0.01% to 3.0% by weight of the toner composition. The alumina particles surface treated with an inorganic/organic compound may be present in the range of 0.01% to 1.0% by weight of the toner composition.
