Zusammenfassung:A toner for developing an electrostatic image comprises primary colored resin particles having a mean particle size of 0.6 to 10 microns which have been agglomerated to form secondary particles having a particle size of 1.2 to 20 microns. The primary colored resin particles are formed from fine elementary particles comprised of one or more polymers and a colorant. Thus, the toner can be economically prepared, is excellent in resolution, does not cause much fogging or scattering, and is excellent in fixability and image density.
