PROBLEM TO BE SOLVED: To provide a developing device capable of preventing the soiling of a toner bottle at the time of developing operation without waste because a toner bottle soiling preventing member need not be provided for each toner bottle. SOLUTION: Even when the toner bottle 33 is not covered over due to spatial restriction because a distance between the bottle 33 and a photoreceptor is short, the aperture part 38a of a bottle holding member 38 is covered with the cylindrical toner bottle soiling preventing member 54 made of thin Mylar(R), so that the soiling of the outer peripheral surface of the bottle 33 is prevented. The member 54 is fit in the member 38 from the above and attached to the aperture part 38a of the member 38 in any unit of the developing device 5 pulled out of an image forming device main body in a state where the bottle 33 is pulled out. |
