ABSTRACT:
A toner composition is obtained by the dispersion polymerization of a monomer in the presence of a charge-controlling agent, a colorant and a specified dispersant of a higher fatty acid salt of a long-chain alkyl or hydroxyalkyl amine, a polyoxyalkene-phenyl or alkylphenyl-ether or a polyethyleneimine. The toner composition is useful for developing an electrostatic image in an electrophotographic process and the like.
