An electrophotographic toner composition is provided. It contains a vinyl polymer having a number average molecular weight of 1,000 - 10,000, a weight average molecular weight/number average molecular weight ratio of 41 - 200, a glass transition temperature of 50 - 70.degree.C, and specific shear rates at 110.degree.C and 190.degree.C respectively. The toner composition affords vivid copy marks even when used in a small amount, and exhibits good fixing property even at low temperatures. |
