Patent ID: 7396625

Claim:
A method for producing a toner comprising: polymerizing at least monomers in at least one of a supercritical fluid and a subcritical fluid to thereby produce toner particles, wherein at least one of the supercritical fluid and the subcritical fluid comprises a fluorine-containing surfactant, wherein a polymer resulted from polymerization of the monomers is insoluble in at least one of the supercritical fluid and the subcritical fluid, wherein the fluorine-containing surfactant is a compound comprising a unit represented by the General Formula (1): where R 1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R 2 represents a substituted or unsubstituted alkylene group having 1 to 4 carbon atoms, and Rf represents a perfluoroalkyl group having 1 to 20 carbon atoms.
