Abstract

The coating of metallic electrostatographic carrier beads may be effected directly by in situ polymerization which is elec-trochemically initiated. The nature of the carrier beads serves as the working electrode thereby inducing polymer coating thereof while forming the polymer in situ. The counter electrode may be a metal electrode located above or around a bed of carrier beads. The beads and the electrode may be placed in an insulating vessel containing sufficient mono-mer to cover the beads and the electrode, Since the beads are in physical contact with each other, they form an electrical network. When a potential is applied, electrochemical initi-ating reactions will occur over the surfaces of the beads.
