  • COATED CARRIER PARTICLES AND PROCESSES FOR FORMING
    Publication number: 20070202428
    Abstract: Carrier core is coated with a coating containing polymer formed in the Presence of a surfactant and conductive particles coated with conductive polymer. The carrier may be formed by forming polymer particles by polymerization in the presence of a surfactant; dry-mixing carrier cores with a powder comprising the polymer particles and conductive particles coated with conductive polymer; and heating the mixture to fuse the powder to the surface of the cores.

  • Carrier composition
    Publication number: 20060099528
    Abstract: A carrier particle for an electrostatographic process, and a developer employing such carrier particle, is provided. The carrier particle includes an irregular shaped ferrite core, and a coating applied to the core. The developer includes a carrier particle comprising the irregular shaped ferrite core and a toner. The irregular shaped ferrite cores and developers exhibit reduced toner aging and/or reduced material performance degradation, while exhibiting excellent triboelectric and conductive properties.
