  • Electrophotographic toner and developer compositions and color reproduction processes using same
    Patent number: 5411833
    Abstract: Toner and liquid developer compositions for use in color electrophotographic processes are described. The developer compositions display high particle-mediated conductivity and charge and thus give rise to a final print of exceptionally high quality. Methods of manufacturing the toner and developer compositions are also disclosed, as are novel charge control agents and processes for using the various compounds and compositions in consecutive multicolor image development.
