Method for producing positive charging toner

摘要

The present teaching provides a method for producing a positive charging toner that can exhibit stable charge characteristics. According to the present teaching, a positive charging toner is produced by preparing a base particle suspension having a conductivity not higher than 70 μS/cm and comprising base particles that are obtained by mixing and emulsifying an aqueous medium and a resin solution containing the polyester resin; producing toner base particles by mixing the base particle suspension with a charge control resin microparticle suspension containing charge control resin microparticles; causing the charge control resin microparticles to adhere to the surfaces of the base particles; and washing the toner base particles.
