  • Carrier coated with acyl modified styrene copolymer, used in electrostatic imaging process
    Patent number: 4156607
    Abstract: Electrostatographic developer compositions for use in developing electrostatic latent images wherein the triboelectric charging potential of functional polymers employed in the carrier materials are controlled through chemical alteration by acylation of hydroxyl and amino functions. The controlled variation of the triboelectric behavior of functional polymers by acylation provides a means of attaining optimum triboelectric responses in development systems.
    Type: Grant
    Filed: September 26, 1977
    Date of Patent: May 29, 1979
    Assignee: Xerox Corporation

  • Inorganic fluoride reversal carrier coatings
    Patent number: 4126458
    Abstract: Electrostatographic developer mixtures comprising finely-divided toner particles electrostatically clinging to the surface of carrier particles comprising a core having an outer coating thereon comprising an inorganic metal fluoride. The carrier particles have negative triboelectric charging properties and are particularly useful in reversal development systems. Imaging processes are also disclosed.
