ABSTRACT:
A color toner for developing electrostatic images is formed of color toner particles each including a binder resin, a polyalkylene, and a colorant. The color toner particles are formed by suspension polymerization. The polyalkylene is characterized by having a crystallinity of 10-50% and a melting enthalpy (as measured by a differential scanning calorimeter) of at most 35 cal/g. The color toner is characterized by an improved fixability without causing offset especially at a relatively low temperature and suitable for providing a transparency film for an overhead projection.
