Patent ID: 8092975

Claim:
A method for producing a toner for developing electrostatic image, comprising a suspending step of suspending a polymerizable monomer composition containing at least a polymerizable monomer and a colorant into an aqueous dispersion medium containing a dispersion stabilizer to yield a suspension wherein droplets of the polymerizable monomer composition are dispersed, and a step of subjecting the suspension to suspension polymerization in the presence of a polymerization initiator to yield colored resin particles, wherein the colorant is a metal-containing organic pigment, and wherein an inhibitor of small diameter microparticle production having a structure represented by the following formula 1, 2, or 3 is added to the aqueous dispersion medium before or after the dispersion stabilizer is added, or before or after the polymerizable monomer composition is charged, in a ratio of 0.01 to 1 part by weight for 100 parts by weight of the polymerizable monomer: wherein R is OX, SO 3 X, CO 2 X, or CH═CHCO 2 X; and X is hydrogen or a metal.
