description A chemically prepared toner composition according to one example embodiment includes a core including a first polymer binder, a second polymer binder, a colorant and a release agent; a shell that is formed around the core and includes a third polymer binder; and a borax coupling agent between the core and the shell. The first and third polymer binders are different amorphous polyester resins. The second polymer binder is a crystalline polyester resin and acts as a plasticizing agent in the core. The borax coupling agent assists in adhering the shell to the outer surface of the core. Optionally, the toner of the present invention may be finished with a set of extra particulate additives.
