<p>PROBLEM TO BE SOLVED: To provide a crystalline polyester which is moderately compatible with an amorphous resin, especially an amorphous polyester having a bisphenol A skeleton and is usable suitably for a toner-binding resin and so on; a polyester resin composition containing the above crystalline polyester; a toner-binding resin containing the above crystalline polyester or the above polyester resin composition; and such a toner for electronic photography that contains the above toner-binding resin. SOLUTION: The crystalline polyester is obtained by polycondensing a monomer containing 0.1-1.0 mole % of a divalent aromatic compound and has a softening point of 85-150 deg.C; the polyester resin composition comprises the above crystalline polyester and an amorphous resin which is obtained by polycondensing a monomer comprising an alcoholic component containing 40 mole % or more of an aromatic compound having a bisphenol A skeleton; the toner-binding resin contains the above crystalline polyester or the above polyester resin composition; and the toner for electronic photography contains the above toner-binding resin.</p> |
