Patent ID: 8501380

Claim:
An electrostatic latent image developing toner comprising: a mother particle that contains a coloring agent, a release agent and a binder resin and an inorganic particle that is added to the surface of the mother particle, wherein: a relation between a relaxation time t and a relaxation modulus G(t) that are determined from the dynamic viscoelasticity measurement made on the toner satisfies the following equations (1) and (2); G ( t 1)<100 Pa (1) 515<( G ( t 2)− G ( t 1))/(log( t 1)−log( t 2))<1,230 (2) and t 1 represents the maximum relaxation time and t 2 represents the minimum relaxation time, the relaxation time t and relaxation modulus G(t) are determined with a sine-wave vibration technique with measurements initiated at a temperature of 100° C. and being made continuously up to 160° C. while sine-wave vibrations are applied at vibration frequency ranging from 0.1 rad/sec to 100 rad/sec, and the toner being contacted with a carrier having a cross-linked melamine resin particle.
