  • Publication number: 20170212439
    Abstract: A toner composition and a method of making a toner composition wherein toner particles having an average size range of 1-25 ?m may be mixed with an extra particulate additives including large silica particles having a primary particle size in the range of 60 nm to 120 nm, medium fumed silica particles having a primary particle size in the range of 30 nm to 60 nm, antimony oxide doped tin oxide (Sb2O5 doped SnO2) coated titania conductive additive and acicular titania oxide. Optionally small silica having a primary particle size in the range of 2 nm to 20 nm may be mixed with the medium silica, large silica, titania conductive additive and the acicular titania oxide. This use of this particular set of titania and silica extra particulate additives in the toner generates less waste toner, increasing toner usage efficiency and significantly reduces toner consumption without impacting image quality and charge characteristics.
