Abstract: A carrier including a carrier core; and a coating thereover; wherein the coating comprises a polymer having a low molecular weight of from about 100,000 to about 300,000 g/mole and a particle size of from about 0.05 to about 0.6 micrometer. A developer including a toner; and a carrier; wherein the carrier comprises a carrier core; and a coating thereover; wherein the coating comprises a polymer having a low molecular weight of from about 100,000 to about 300,000 g/mole and a particle size of from about 0.05 to about 0.6 micrometer. A process for preparing a carrier including providing a carrier core; and disposing a polymer coating thereover by combining the carrier core and the polymer coating in a mixing device; optionally, fusing the coating to the carrier core; wherein the coating comprises a polymer having a low molecular weight of from about 100,000 to about 300,000 g/mole and a particle size of from about 0.05 to about 0.6 micrometer.
