Zusammenfassung:The present invention addresses the problem of providing an electrophotographic toner which has excellent storage property, is excellent in offset resistance and low-temperature fixing property during printing and has few substances causing staining with time, odor or dust inside a copy machine or a printer. The present invention relates to an electrophotographic toner characterized by containing an ethylene copolymer which comprises a constituent unit (a) derived from ethylene in an amount of 80 to 99.5% by mol and a constituent unit (b) derived from a cyclic olefin of 8 or more carbon atoms in an amount of 0.5 to 20% by mol [(a)+(b)=100% by mol] and satisfies the requirements: (i) the intrinsic viscosity [·] is in the range of 0.01 to 0.50 dl/g, and (ii) the crystallinity is in the range of 50 to 90%.
