ABSTRACT:
An electrostatic latent image developing toner including, as a binder resin, a crystalline resin and at least one kind of non-crystalline resin, wherein, in a dynamic viscoelasticity measurement by a sine wave vibration method, a minimum value of the relaxation elasticity H in a relaxation spectrum obtained from frequency dispersion characteristics measured at temperatures of 60 and 80 degrees centigrade with a measurement frequency set in the range of 0.1 to 100 rad/sec and measurement strain set in the range of 0.02 to 4.5% is in the range of 10 to 900 Pa/cm2, and a relaxation time λ corresponding to the minimum value is in the range of 1 to 10,000 sec.
