Abstract
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.
