A toner for developing electrostatic images, comprising a binder resin and a colorant, the binder resin including a crystalline polyester resin and an amorphous resin. When, in differential scanning calorimetry of the toner according to ASTM D3418-8, the temperature of the endothermic peak derived from the crystalline polyester resin in a first heating process is defined as Tm1 (° C.), the endothermic quantity based on the endothermic peak in the first heating process is defined as &Dgr;H1 (mW/g), and the endothermic quantity based on the endothermic peak in a second heating process is defined as &Dgr;H2 (mW/g), Tm1 is 50 to 80° C., and &Dgr;H1 and &Dgr;H2 satisfy the relationship represented by the following Formula (1). When the softening temperature of the toner is defined as Tf1/2 (° C.), Tf1/2 is 85 to 135° C. Tm1 and Tf1/2 satisfy the relationship represented by the following Formula (2): 0.35≦̸&Dgr;H2/&Dgr;H1≦̸0.95  Formula (1) Tf1/2≦̸205−(1.4×Tm1)  Formula (2).
