METHOD FOR PREPARING TONER

摘要

PURPOSE: A method for manufacturing a toner is provided to reduce the particle distribution of toner particles and use a polyester resin as a binding resin. CONSTITUTION: A polyester resin dispersing solution, a coloring agent dispersing solution, and a wax dispersing solution are mixed. A coagulating agent is added to the mixed solution in order to coagulate toner particles. The toner particles are united. Inorganic base is used as a dispersion stabilizing agent for the polyester resin dispersing solution. The coagulating agent is inorganic salt. The concentration of monovalent metal ions of the inorganic base, the concentration of trivalent metal ion of the inorganic salt, and the concentration of the hydrogen ions of acid added in a coagulating process satisfy a relative formula, -11<log(M1^+)(M2^3+)(H^+)<-6.
