ABSTRACT:
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.
