The disclosure provides a toner composition comprising toner particles with a core and a shell, wherein the core comprises a polyester polymer and a styrene acrylate polymer, and the shell comprises a polyester polymer and, optionally, a styrene acrylate polymer, either or both of which can be the same or different from that in the core.

Toner particles comprising both polyester and styrene acrylate polymers having a polyester shell

A method for the continuous aggregation of pre-toner particles including continuously flowing a slurry that includes at least one resin, and optionally includes other components used in forming aggregated pre-toner particles, or continuously flowing individual dispersions of the components of the slurry, into a reactor. The reactor includes a cylinder with a cylindrical channel, a mixing shaft located in the cylindrical channel, a longitudinal axis of the mixing shaft is substantially parallel to a longitudinal axis of the cylinder, at least one blade that has a plurality of holes is attached to the mixing shaft. The slurry or the dispersions are continuously mixed to form aggregated pre-toner particles.
