  • Toner compositions
    Patent number: 5763132
    Abstract: A process for decreasing toner adhesion and decreasing toner cohesion which comprises adding a spacer component of a polymer, a metal, a metal oxide, a metal carbide, or a metal nitride, to the surface of a toner comprised of resin, wax, compatibilizer, and colorant excluding black, and wherein toner surface additives are blended with said toner, and wherein said component is permanently attached to the toner surface by the injection of said component in a fluid bed milling device during the size reduction process of said toner contained in said device, and where the power imparted to the toner to obtain said attachment is from equal to, or about above 5 watts per gram of toner.
