Process for Producing Resin Microparticles for a Toner Raw Material

Abstract

An object of the present invention is to provide a resin microparticle for a toner raw material that has a small particle diameter and a narrow particle diameter distribution and has a low odor. There are provided a resin microparticle for a toner raw material characterized in that all of the following requirements (i) to (iii) are satisfied: Requirement (i): A particle diameter of 50% volume (D50) satisfies the relationship 0.05 μm≦D50≦1 μm; Requirement (ii): A particle diameter of 10% volume (D10) and a particle diameter of 90% volume (D90) satisfy the relationship D90/D10≦7; and Requirement (iii): The content of an organic solvent is not more than 70 ppm.
