A two component development system includes a plurality of toner particles that include a colorant and a plurality of toner carrier particles that include a magnetic carrier core having a Ddiameter in a range from about 30 microns to about 40 microns, and a surfactant-polymer coating, the coating being present in an amount in a range from about 0.5 percent by weight to about 1.5 percent by weight of the toner carrier particle.

Carrier for two component development system

Disclosed is a carrier suitable for use with an electrophotographic developer and an electrophotographic developer containing the carrier. In particular, the carrier is powder coated and comprises a copolymer of cyclohexylmethacrylate and dimethylaminoethylmethacrylate.

Carrier and developer

A carrier comprised of a core, and thereover a polymer coating containing a first polymer and a silicone resin, and which resin possesses an average diameter of from about 300 to about 3,000 nanometers.

Coated carrier

Carrier comprised of a core, a polymer coating, and wherein said coating contains a conductive polypyrrole contained in a carbon black matrix; or a polyaniline contained in a carbon black matrix.

Coated conductive carriers

A toner of toner particles containing at least one binder, at least one color ant, and an external additive package comprised of zinc stearate and at. least one of silicon dioxide or titanium dioxide, wherein the amount of zinc stearate is limited to about 0.10 percent by weight or less of the toner. It has been surprisingly found that when the amount of zinc stearate is so limited, a developer formed from the toner exhibits excellent triboelectric charging and stability and excellent developer flow. When the developer is used in a magnetic brush development system, consistent, high quality copy images are formed substantially without any depletion defects over time.
