PRODUCTION METHOD OF TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a production method of a toner for developing an electrostatic charge image, the toner giving sufficient coloring power and transfer property.

SOLUTION: A method includes the steps of: obtaining core particles by aggregating phthalocyanine compound particles made of a phthalocyanine compound represented by general formula (A) (where M represents a metal atom or TiO) on the surfaces of aggregated particles in an aqueous medium, the aggregated particles obtained by aggregating core resin fine particles made of a core resin containing a styrene-acrylic resin with carbon black particles having a pH of 2 to 6; and aggregating shell resin fine particles made of a shell resin containing a styrene-acrylic modified polyester resin having a styrene-acrylic polymer segment coupled to an end of a polyester segment, on the surfaces of the above core particles.
