Abstract: A toner includes particles of a resin, an optional colorant, a first crystalline polymeric wax and a second crystalline polymeric wax, where the first crystalline polymeric wax is a crystalline polyethylene wax, the second crystalline polymeric wax is selected from aliphatic polar amide functianalized waxes, carboxylic acid-terminated polyethylene waxes, aliphatic waxes consisting of esters of hydroxylated unsaturated fatty acids, high acid waxes, and mixtures thereof, and the toner particles are prepared by an emulsion aggregation process.

Abstract: Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presenc e of a coagulant, aggregating to form particles, coalescing to form fused particles , and removing the fused particles from the aqueous dispersion. Wax dispersions ca n be added either after mixing or during aggregation, so that wax is excluded fro m the core of the toner particles.

Abstract: Toner particles are provided which may, in embodiments, include a core and a shell. In embodiments, charge control agents may be co-emulsified with a resin utilized to form a shell. The shell may prevent a crystalline resin in the core from migrating to the toner surface. Inclusion of the charge control agent in the shell itself may provide the resulting toner particles with desirable charge characteristics and sensitivity to relative humidity.

Abstract: Toner compositions include a non cross linked resin; a cross linked resin or gel; a wax; and a colorant. Processes for preparing a toner include mixing a non-cross linked resin and a cross-linked resin or gel in the presence of a wax, a colorant, and a coagulant to provide toner size aggregates; adding additional non-cross linked latex to the formed aggregates thereby providing a shell over the formed aggregates; heating the shell covered aggregates to form toner; and, optionally, isolating the toner.
