Abstract
A crystalline polyester obtained by polycondensing monomers comprising 0.1 to 10% by mol of a divalent aromatic compound, wherein the crystalline polyester has a softening point of 85° to 150° C. The crystalline polyester can be suitably used for a resin binder for toner for electrophotography and the like used for developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing, and the like; a polyester resin composition comprising the crystalline polyester.
