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. |
