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 ΔH1 (mW/g), and the endothermic quantity based on the endothermic peak in a second heating process is defined as ΔH2 (mW/g), Tm1 is 50 to 80° C, and ΔH1 and ΔH2 satisfy the relationship represented by the following Formula (1). When the softening temperature of the toner is defined as Tf 1/2 (° C.), T f1/2 is 85 to 135° C. Tm1 and T f1/2 satisfy the relationship represented by the following Formula (2):n n0.35≦ΔH2/ΔH1≦0.95 Formula (1)n nT f1/2 ≦205−(1.4×Tm1) Formula (2). |
