PRODUCTION PROCESS OF TONER BY DENEUTRALIZATION SUSPENSION METHOD

摘要

PURPOSE: Provided is a production process of a toner by deneutralization suspension method which lets the toner particle formed by suspension process accompanied by deneutralization so that it produces the particle composition in the water quickly. CONSTITUTION: The production process of the toner by deneutralization suspension method comprises the steps of: (i) mixing 5-90wt% of acrylate and 30-90wt% of linear low molecular resin complex styrene with carboxyl group formed at the end of a toner binding resin molecule to prepare resin composition; (ii) neutralizing the resin composition in alkali compound and dissolving it in water and adding a coloring agent, a charge controlling agent and a releasing agent to water dispersion resin solution to prepare colored resin dispersion material; and (iii) adding the colored resin dispersion material to acidic compound and reversely neutralizing to produce toner particle composition with 5-10 micrometers in diameter, with stirring to stabilize a toner particle.
