PURPOSE:To obtain a toner containing an electrification controller in a sufficient dispersion state, and capable of forming an image high in quality by dispersing said controller into a monomer in the presence of a higher fatty acid salt of long-chain alkyl or hydroxyalkyl amine specified in structure. CONSTITUTION:The electrification controller and the colorant, such as carbon black are dispersed into the polymerizable monomer and suspension polymerized in the presence of the higher fatty acid salt of the long-chain alkyl or hydroxyalkyl amine represented by the formula shown on the right in which each of R1-R4 is 8-20C long-chain alkyl or alkenyl or the like, and R5 is 8-18 alkyl or alkenyl, thus permitting the electrification controller to be easily dispersed finely and uniformly into the monomer without being coalesced by the electrification stabilizer and localized to the surface of each toner particle during the suspension polymerization, and accordingly, the superior toner to be synthesized. |
