摘要

An electrostatic latent image developing toner includes a mother particle which contains a coloring agent, a release agent and a binder resin; and an inorganic particle which is added to the surface of the mother particle, and wherein a relation between a relaxation time t and a relaxation modulus G(t) which are determined from the dynamic viscoelasticity measurement made on the toner satisfies the following equations (1) and (2); G(t1)<100 Pa(1) 515<(G(t2)-G(t1))/(log(t1)-log(t2))<1,230(2) wherein t1 represents the maximum relaxation time and t2 represents the minimum relaxation time.
