High-resolution electrophotographic printers need toner with small par
ticles. This paper describes producing a polymerized toner with small
particles directly by emulsion polymerization, and applying the toner
to a nonmagnetic monocomponent development process. The emulsion polym
erized toner is produced by putting together fine-grain emulsion parti
cles and heat-welding them on contact. Toner particle shape, binder po
lymer composition, and molecular weight were all optimized for nonmagn
etic monocomponent development.
