ABSTRACT:
A toner for developing a latent image includes, at least, a binder resin, a releasing agent, a coloring agent and a fluidizing agent. A melting point Tw of the releasing agent is higher than or equals to a softening temperature Ts of the developer measured by a capillary rheometer of a constant shear stress type. The melting point Tw of the releasing agent is lower than or equals to a melting temperature Tm of the developer measured by ½ method. Using the above described toner, it becomes possible to print a full color image at a high speed without causing an offset phenomena or sheet jam.
