A toner for electrostatic image development containing at least a resin binder, the resin binder being composed of a crystalline resin and an amorphous resin, wherein the crystalline resin contains a crystalline polyester obtained by polycondensing an alcohol component containing an aliphatic diol having 2 to 10 carbon atoms and a carboxylic acid component containing an aromatic dicarboxylic acid compound and an aromatic tricarboxylic or higher polycarboxylic acid compound, wherein the crystalline polyester has a weight-average molecular weight of from 20,000 to 150,000, and wherein the crystalline resin and the amorphous resin are in a weight ratio, i.e. crystalline resin/amorphous resin, of from 55/45 to 95/5. The toner for electrostatic image development of the present invention can be suitably used in, for example, the development or the like of latent image formed in electrophotography, an electrostatic recording method, an electrostatic printing method, or the like.
