TONER FOR ELECTROSTATIC IMAGE DEVELOPMENT AND PRODUCTION METHOD THEREFOR

WIPO Patent Application WO/2013/145877

A1

Provided are: a toner for electrostatic image development that suppresses the generation of odors when the toner is fixed and which has excellent fixing properties; and a production method therefor. The production method for the toner for electrostatic image development has: a polymerization step in which at least one type of monovinyl monomer selected from a group comprising styrene and styrene derivatives, at least one type of cross-linking divinyl monomer selected from a group comprising divinyl benzene and divinyl benzene derivatives, and a polymerizable monomer composition containing a coloring agent are polymerized in an aqueous medium in the presence of a polymerization initiator, and colored resin particles are formed; and a stripping step in which volatile matter residual in the colored resin particles in the aqueous medium is removed. The production method for the toner for electrostatic image development is characterized by the diethylbenzene content in the colored resin particles after the polymerization step and before the stripping step being 100-400 ppm, as a result of the polymerization step; and, after the stripping step, the diethylbenzene content in the colored resin particles being 30-250 ppm and the monovinyl monomer content being no more than 30 ppm, as a result of the stripping step.
