Abstract

Disclosed is an improved toner composition comprised of a colorant and a copolycarbonate resin, which toner has an intrinsic viscosity of from about 0.10 to about 0.6 dl/gr. (deciliters per gram) a melt flow temperature (T.sub.f) of from about 70.degree. C. to about 125.degree. C., a flash fusing energy of from about 3 J/in..sup.2 to about 8 J/in..sup.2, (Joules per inch squared), and a glass transition temperature of from about 50.degree. C. to about 65.degree. C.
