Beschreibung
Zusammenfassung:	A resin binder composition for toners, containing a polyester resin A which is a polycondensate A of raw materials A containing an alkylene oxide adduct of bisphenol A, an aromatic dicarboxylic acid compound, a trivalent or higher polyvalent raw material monomer which is at least any one members of a trihydric or higher polyhydric alcohol and a tricarboxylic or higher polycarboxylic acid compound, and an amorphous acid modified product A of an α-olefin polymer having 4 or more carbon atoms and 18 or less carbon atoms, the polyester resin A having a softening point of 120°C or more and 150°C or less; and a toner for electrostatic image development, containing these resin binder composition for toners. The resin binder composition for toners of the present invention is suitably used for a toner for electrostatic image development which is usable in development of latent images formed in, for example, electrostatic image development method, electrostatic recording method, electrostatic printing method or the like.
