description 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 large fumed silica particles sized 70 nm to 120 nm and medium fumed silica particles sized 30 nm to 60 nm and optionally alumina particles surface treated with an inorganic/organic compound. The large sized fumed silica particles are present in the range of 0.1% to 2% by weight of the toner composition. The medium sized fumed silica particles are present in the range of 0.1% to 2% 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.
