An electrophotographic toner used for an image forming method that utilizes a heat-pressure type fuser equipped with a fusing member having a surface layer containing polybenzimidazole, wherein the toner comprises at least cycloolefin copolymer resins as binder resins. The cycloolefin copolymer resins comprise a mixture of 0 to 75 percent by weight of a low molecular weight component having a weight-average molecular weight of less than 15000, 5 to 25 percent by weight of a medium molecular weight component having a weight-average molecular weight of 15000 to 100000, and 20 to 95 percent by weight of a high molecular weight component having a weight-average molecular weight of more than 100000.
