Abstract:
A method of manufacturing an electrostatic image-developing toner, comprisingpolymerizing by emulsion polymerization a monomer in the presence of a charge controlling agent to form a polymer of fine particles having a mean particle size of 0.01-1 .mu.m, wherein said charge controlling agent is present in an amount of from 0.5 to 10 parts by weight based on 100 parts of said polymer;mixing said fine particles with core particles;adhering said fine particles to the surfaces of said core particles;wherein said charge-controlling agent is a compound represented by general formula (1):A--(X--B) n (1),wherein A represents an aromatic ring residue which may have a substituent;B represents an aromatic ring residue which may have a substituent, an aliphatic residue which may have a substituent, or a hydrogen atom;X represents --CONH--, --NHCO--, or --NHCONH--; andn represents an integer in the range from 1 to 3.
