Abstract
A process for the preparation of conductive carrier particles which comprises mixing carrier core with a first polymer pair and a second polymer pair, heating the mixture, and cooling the mixture; and wherein the first and second polymer pair each contain an insulating polymer and a conductive polymer and wherein the carrier conductivity thereof is from about 10.sup.-6 to about 10.sup.-14 (ohm-cm).sup.-1.
