PURPOSE:To provide a toner which can be stably electrostatically charged by coating electrostatically chargeable particles on the surface of the toner base body which does not contain an electrostatic charge control agent. CONSTITUTION:The chargeable particles 2 are coated on the outside surface of the toner base body 1 which does not contain the electrostatic charge control agent. The toner is thereby stably electrostatically charged and the fluctuation in the electrostatic charge quantity of the toners by lots is eliminated. Since the need for recontrol of the electrostatic charge quantity of the toner by an external additive is eliminated, the cost of the external additive is reduced. Furthermore, the flowability of the toner is obtd. by using the chargeable particles having good flowability. |
