An electrophotographic toner includes a binder resin, a colorant, and a releasing agent, wherein the electrophotographic toner has a complex viscosity (.eta.) of 4e2 Pas to 8e3 Pas at a temperature range of 120 to 160.degree. C. and an angular velocity range of 1.6 to 10 rad/s, a rate of change of the complex viscosity of 165 to 185 Pas/.degree. C. at 1.6 rad/s, and 70 to 80 Pas/.degree. C. at 10 rad/s within the temperature range, a stress relaxation of 1.0 e3 to 4.5 e4 Pa at a relaxation time of 0.05 to 0.3 seconds under a temperature range of 120 to 160.degree. C., and a rate of change of the stress relaxation (.DELTA.G/.DELTA.T) of 785 to 1000 Pa/.degree. C. at 0.05 seconds and 190 to 215 Pa/.degree. C. at 0.3 seconds within the temperature range above.
