    摘要: A method for manufacturing an electrophotographic toner having a mean particle diameter of more than 5 &mgr;m and less than 10 &mgr;m. For manufacturing the above size of toner, coarsely pulverized particles are pulverized to medium pulverized particles having a mean particle diameter of more than 10 &mgr;m and not more than 19 &mgr;m at first. Subsequently, the medium pulverized particles are further pulverized to small diameter particles having a mean particle diameter of more than 5 &mgr;m and less than 10 &mgr;m, and thereafter the small diameter particles are classified by a rotor type classifier.

    摘要: The present invention relates to a color toner, to the surface of which a small amount of charge-giving agent is fixed. The amount of the charge-giving agent is usually 0.03% to 0.65% by weight of toner, and it becomes still smaller when the resin composing the toner is made from a monomer including a nitrogen containing polar functional group or fluorine containing polar functional group. This composition enables the toner to be charged stably in a narrow charge distribution, thereby decreasing the fog and flying of toner, and resulting in a distinct color image without any turbidity in color.
