It is an object of the present invention to provide a resin composition for a toner and a toner excellent in low temperature fixation property, high temperature offset resistance, blocking resistance, and excellent in coloration.The present invention relates to a resin composition for a toner, which contains a crystalline polymer having a melting point of 180 to 280.degree. C. and heat absorption of 25 to 150 mJ/mg at a melting point measured by a differential scanning calorimeter (DSC) and a non-crystalline polyester having a glass transition temperature of 30 to 80.degree. C.
