Abstract: The presently disclosed embodiments relate in general to toners for use in electrophotographic apparatuses, such as printers and copiers. More particularly, a toner formulation of at least one binder, at least one colorant, and an embrittling agent, and methods for making the same, is provided wherein the embrittling agent increases grinding rate of the toner formulation.

Abstract: A toner disclosed that includes a binder, at least one colorant and at least one wax, wherein the binder includes an amorphous polyester material, a crosslinked polyester material, a crystalline polyester material, and wherein the toner has a glass transition temperature of from about 35° C. to about 60° C.
