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