AQUEOUS DISPERSION LIQUID OF RESIN PARTICLE AND METHOD FOR MANUFACTURING THE SAME, TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT AND METHOD FOR MANUFACTURING THE SAME, ELECTROSTATIC CHARGE IMAGE DEVELOPER, IMAGE FORMING METHOD, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an aqueous dispersion liquid of resin particles and a method for manufacturing the aqueous dispersion liquid with a simple manufacturing process and excellent dispersibility of resin particles, and to provide a toner for electrostatic charge image development and a method for manufacturing the toner improved in maintaining property of picture quality when continuously used for a long period of time even under high temperature and high humidity conditions.

SOLUTION: The aqueous dispersion liquid of resin particles contains a polymer dispersant by 0.1 to 30 wt.% with respect to a resin solid content, the polymer dispersant having a weight-average molecular weight of not less than 5,000 and comprising a condensate of a monomer having polycondensation property and containing a hydroxycarboxylic acid that has hydroxy groups and carboxy groups in total not less than three. The toner for electrostatic charge image development is produced by using the above aqueous dispersion liquid of resin particles.
