METHOD FOR MANUFACTURING DEVELOPER AND DEVELOPER

摘要

PROBLEM TO BE SOLVED: To provide a developer which attains small particle size and shape control without using organic solvent, has small variation in surface composition and has good fixing ability and transfer ability. SOLUTION: The method for manufacturing the developer includes steps of: mixing a resin having a dissociable functional group with an aqueous medium; subjecting the obtained mixture liquid to mechanical shearing; finely pulverizing the pulverized mixture to form resin microparticles; adding a dispersion of colorant particles; and causing the resin microparticles and colorant particles to agglomerate to form toner particles.
