  • Toner formulations
    Patent number: 6534230
    Abstract: A dry, powder electrostatic toner having polyester resin as a binder, pigment as a colorant, charge control ingredients polyethylene wax as a release agent, and extra particulate elements to improve flow and to scrub the doctor blade, one extra particular element is hydrophilic rutile acicular titanium oxide with aluminum oxide surface treatment, two silicas are blended within the bulk of the toner, one of BET surface area of about 30 m2/g and one of BET surface area of about 380 m2/gn; and an organoboron complex negative exchange control agent is blended with a quaternary ammonium salt of an aluminosilicate compound negative charge control agent. Improved functioning as a toner is realized.
