To keep xerographic toner from caking or fusing during processing, storage and use, fine powders known as anti-caking agents are often added to the toner. These agents are inherently less susceptible to caking and lumping, and they operate by adhering to and covering the surface of toner particles. Thin, uniform coverage is not always obtained, however, and in such cases caking can be increased rather than reduced.
