ABSTRACT:
A magenta toner for developing an electrostatic image is formed of magenta toner particles containing at least a binder resin and a magenta pigment. The magenta pigment is a solid solution pigment comprising C.I. Pigment Red 122, C.I. Pigment Red 202 and C.I. Pigment Violet 19. The magenta toner particles are preferably formed by suspension polymerization of a polymerizable monomer mixture including a polymerizable monomer and the solid solution pigment in an aqueous medium.
