摘要： Provided is a method for producing a toner having excellent particle size distribution and storage stability. The method set forth in the present specification is a method for producing a toner by aggregating and fusing base microparticles whose main component is a binder resin including anionic groups, wherein an aggregate is produced by aggregating the base microparticles in a base microparticle suspension, in a presence of a non-ionic surfactant such that a surface tension of an aqueous solution thereof is not lower than 45 mN/m at any concentration at or above a critical micelle concentration, and the toner is produced through fusion of the aggregate. According to this method, drops in a glass transition temperature of the toner can be curbed, and the toner having excellent storage stability and good particle size distribution can be obtained.

摘要： Spherical-shaped liquid droplets are made by dispersing oil phase containing: a resin with an acid group, a first hydrophobic solvent effecting dissolution of the resin, a colorant, and a charge control agent which is positively charged in an aqueous dispersion medium in the presence of a base; and the liquid particles are solidified to be solid particles by removing the first solvent from the liquid droplets. The solid particles obtained in this manner are washed with a second solvent. As the second solvent, a solvent which dissolves the charge control agent and but does not dissolve the resin such as alcohol is selected. Accordingly, the charge control agent in the solid particles are made to elute to the outer surface layer of the solid particles, thereby improving the positive chargeability of the solid particles.
