A conductive carrier composition comprised of a core with a coating thereover comprised of a mixture of first and second polymers, and wherein the first polymer contains a conductive component, and the second polymer contains a metal oxide.

Conductive developer compositions with coated carrier particles

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.

Coated carrier particles and processes thereof

A process for 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.
