<P>PROBLEM TO BE SOLVED: To solve the problem that there is possibility that a hook portion 2a of a coupling portion 2 is not appropriately disengaged from a driving ring 3 even if a release ring 4 is made to work on a release projection 2b of the coupling portion 2 when removing a toner bottle 1. <P>SOLUTION: The driving ring 3 is slidably provided. When the release ring 4 is made to work on the release projection 2b of the coupling portion 2, drive coupling between a driving gear 6 provided integrally with the driving ring 3 and a motor gear 8 connected to a driving motor 9 is cut off. Therefore, when the release ring 4 is made to work on the coupling portion 2, rotational load applied to the driving ring 3 from the driving motor 9 is released, and the hook portion 2a of the coupling portion 2 is appropriately disengaged from the driving ring 3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
