Dual pigment compositions are provided that include a first pigment based upon a xanthene dye and a second pigment based upon a monoazo dye. The pigment compositions of the present disclosure may be combined with a binder resin to form a toner, in embodiments a magenta toner.

Dual pigment toner compositions

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

A carrier composition having magnetite with a diameter of from about 80 microns to about 150 microns, and wherein the carrier has a conductivity of from about 10to about 10(ohms-cm)and a carrier breakdown voltage of from about 20 to about 200 volts, and a developer composition with toner and this carrier composition, and also including a developer housing apparatus and an electrostatographic apparatus comprising the developer housing apparatus.

Carrier and developer compositions

Super wire history image defects in an image development system including one or more electrode wires disposed in a gap between a toner donor roll and an imaging member are reduced by providing an initial toner composition in the image development system, the initial toner composition containing at least 30 number % fine particles having a particle size no greater than 5 &#x3bc;m; and providing replenisher toner into the development system to replenish the toner used to produce images by the image development system; the replenisher toner containing 20 number % or less fine particles having a particle size no greater than 5 &#x3bc;m.
