Patent ID: 7402370

Claim:
A toner for developing electrostatic images in a single component development (SCD) system and including toner comprising emulsion aggregation toner particles comprising a styrene acrylate polymer binder, at least one release agent and at least one colorant, wherein the toner particles have a volume average particle size of from about 5 μm to about 10 μm, an average circularity of about 0.95 to about 0.99, a volume and number geometric standard deviation (GSD v and n ) of from about 1.10 to about 1.30, and an onset glass transition temperature of from about 45° C. to about 65° C., wherein the toner particles further include a shell layer thereon comprising a styrene acrylate polymer, and wherein the styrene acrylate polymer of the shell layer and the styrene acrylate polymer binder are the same or are composed of a similar polymer with different chemical and physical characteristics.
