PROBLEM TO BE SOLVED: To stabilize the quantity of developer in a developer storage part, to eliminate such a state that the developer becomes like a cave and to reduce a manufacturing cost by obtaining such constitution that a stirring member is actuated at the same time that a carrying screw is actuated when toner is carried to a developing unit from the storage part. SOLUTION: When a toner bottle 5 is rotated by the action of a driving source for a toner bottle 15 through a rotor 11, a one-way clutch incorporated in a gear 32 is actuated, integrated with the driving shaft 29 of the stirring member 28 and connected to the driving source 15. On the other hand, a gear 30 becomes free from the shaft 29 of the stirring member 28 by the action of the incorporated one-way clutch. That means, when the bottle 5 is rotated so that the toner is supplied to the storage part 1, the stirring member 28 is also actuated at the same time that the bottle 5 is actuated. On the other hand, when the toner is carried to the developing unit G from the storage part 1, the stirring member 28 can be actuated at the same time that the carrying screw 22 is actuated. Thus, since a driving source is not required for the stirring member, the manufacturing cost is reduced. |
