An electrophotographic toner comprising a resin, a colorant and a release agent which comprises a first wax and a second wax, wherein: (i) the first wax exhibits: an endothermic peak appearing in the range 75 -100°C, a peak width at half height of the endothermic peak of 10 - 40°C, an exothermic peak appearing in the range 70 - 100°C and a peak width at half height of the exothermic peak of 10 - 40°C, in a DSC measurement; (ii) the second wax exhibits: an endothermic peak appearing in the range 60 - 90°C, a peak width at half height of the endothermic peak of 5°C or less, an exothermic peak appearing in the range 55 - 80°C and a peak width at half height of the exothermic peak of 5°C or less, in the DSC measurement; (iii) a weight ratio of the first wax to the second wax is between 9:1 and 2:8; and (iv) the resin contains a polar group.
