Abstract

Toner particles are provided which may, in embodiments, include a core possessing at least one polyester resin in combination with a colorant, optional wax, and optional other additives, and a shell over the core including a high molecular weight amorphous polyester resin. The high molecular weight amorphous polyester resin in the shell may prevent any crystalline polyester resin in the core from migrating to the toner surface.
