摘要：A toner for electrostatic charge developing prepared by a production methodincluding aggregating one or more kind of particles in a raw material dispersion includingthe particles to form aggregated particles, and coalescing the aggregated particles byheating. At least one kind of the particles is resin particles including an amorphouspolyester resin synthesized by copolymerizing one or more polyvalent carboxylic acidsand two or more polyhydric alcohols; at least one of the polyvalent carboxylic acids ispolyvalent carboxylic acid having a sulfonic acid group; two of the polyhydric alcohols arean ethylene oxide adduct of bisphenol A and a propylene oxide adduct of bisphenol A;and the following equation (1) is satisfied. 10/90≦()/()≦90/10 Equation (1) In theequation (1), BPA(EO) represents a total mole amount of the ethylene oxide adduct ofbisphenol A used in synthesis of the amorphous polyester resin, and BPA(PO) representsa total mole amount of the propylene oxide adduct of bisphenol A used in synthesis of
the amorphous polyester resin.
