ABSTRACT:
A toner for developing electrostatic images in a single component development (SCD) system free of carrier and including emulsion aggregation toner particles of 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 (GSDv 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., is ideally suited for forming an image using a single component image forming device.
