摘要： The present invention provides an aqueous dispersion of nonspherical fine resin particles having excellent storage stability and processability such as aggregation and adherence to other substances, a method for producing the aqueous dispersion of fine resin particles, and a method for producing toner particles using the aqueous dispersion of fine resin particles. The present invention relates to an aqueous dispersion of fine resin particles characterized in that the fine resin particles are nonspherical particles with an average minor axis being 0.02 μm or more and 1.00 μm or less and an average ratio of a major axis to a minor axis being 2.0 or more and 5.0 or less, a method for producing the aqueous dispersion of fine resin particles, and a method for producing toner particles using the aqueous dispersion of fine resin particles.

摘要： A process for producing a core-shell toner is provided in which the toner has core particles containing at least a binder resin (1), a colorant and a release agent and shell layers which contain at least a resin (2) and with which the core particles are covered; and the process including the steps of (A) mixing a binder resin-(1) dispersion, a colorant dispersion and a release agent dispersion, (B) adding to a mixed dispersion thus obtained an agglomerating agent to effect agglomeration, (C) adding to core agglomerated particles thus formed a mixture prepared by mixing the resin-(2) dispersion and a metal salt to make the resin (2) adhere to the surfaces of the core agglomerated particles, and (D) heating core-shell agglomerated particles thus formed to a temperature not lower than the glass transition temperatures of the binder resin (1) and resin (2) to effect fusion thereof.
