<p>PROBLEM TO BE SOLVED: To provide a manufacturing method of a toner for electrostatic latent image development capable of suppressing the generation of aggregated particles of resin fine particles being a shell material.SOLUTION: A manufacturing method of a toner for electrostatic latent image development includes the steps of: stirring an aqueous medium dispersion (Z) obtained by mixing an aqueous medium dispersion (X) including toner core particles and an aqueous medium dispersion (Y) including resin fine particles; and forming a shell layer comprising the resin fine particles on the surface of the toner core particles. In the aqueous medium dispersion, a zeta potential of the toner core particles and a zeta potential of the resin fine particles are made to have reverse polarity to each other; the conductivity of the aqueous medium dispersion (X) is made to be equal or less than a predetermined value; and the aqueous medium dispersion (Z) is stirred at a predetermined average flow rate or more.</p> |
