Abstract: A process and system for making a resin emulsion suitable for use in forming toner particles including a silicone free anti-foam agent to control foam during formation of a polyester dispersion.

Abstract: A toner particle has a core and a shell surrounding the core, wherein the shell contains a polymerized charge enhanced spacer particle, which is a copolymer of a charge control agent and a monomer. A method of making toner particles includes forming a slurry by mixing together a first emulsion containing a resin, optionally a wax, optionally a colorant, optionally a surfactant, optionally a coagulant, and one or more additional optional additive, heating the slurry to form aggregated particles in the slurry, forming a second emulsion containing a monomer and a charge control agent, polymerizing the second emulsion to form a copolymer of the monomer and the charge control agent, and incorporating the copolymer into the toner particles, wherein the aggregated particles form a core of the toner particles.

Abstract: The present disclosure provides polyesters suitable for use in forming toners. In embodiments, a polyester may be subjected to phase inversion emulsification, in which charge control agents are added so that the polyester emulsion includes charge control agents therein. The resulting polyester emulsion with charge control agents may then be utilized to form toner particles.

Abstract: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex and reduce the particle size of the resulting latex particles and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.
