ABSTRACT:
A toner composition for use in a xerographic or electrostatographic imaging process. The toner composition includes a toner particle and an optional primary external surface additive and a friable external surface additive. The friable external surface additive may also be a material that is capable of functioning as a primary external surface additive. The friable external surface additive is generally larger than the primary surface additive and capable of having portions of the friable particle broken or abraded off during the imaging process. The particles that are abraded off the friable additive can replace the primary external additive particles that become embedded into toner particles during the development process. The friable additives contribute to reducing toner aging and provide a toner with satisfactory flow and triboelectric properties.
