    Abstract: A toner having a crystalline or semi-crystalline polyester resin, an amorphous resin and a colorant. The toner preferably exhibits a resistivity of at least 1×10 11 ohm-cm. A developer may be produced including the toner and optionally a carrier. If a carrier is included, the carrier preferably exhibits a resistivity of greater than 1×10 7 ohm-cm. An electrophotographic machine includes the toner exhibiting high resistivity.

    Abstract: A toner composition includes toner particles including a polymeric resin, a colorant, a wax, and an optional coagulant, and a coagulant applied as a surface additive to a surface of the toner particles to alter a triboelectric charge of the toner particles.

    Abstract: A method of making particles suitable for use as toners includes forming a mixture of sulfonated polyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during the aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. The complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.
