PROBLEM TO BE SOLVED: To prevent toner soiling due to toner scattering by providing a moving means which applies driving force to move a stopper in an opening/closing direction to the moving member side of an opening/closing means but prevents the movement from the moving member side. SOLUTION: The opening/closing means 3 is provided at a position opposed to the stopper 1b opening/closing an aperture 1a for discharging toner 7 from the end on the inner side of a toner container 1 housed in a toner container housing part 2. Then, the aperture 1a of the container 1 housed in the housing part 2 is opened/closed by the stopper 1b by moving the moving member 3a in a direction shown by an arrow A1 or an arrow A2 . Meanwhile, the moving means 4 is constituted to apply the driving force to move the stopper 1b in the opening/closing direction, that is, the direction shown by the arrow A1 or A2 to the moving member 3a side of the opening/closing means 3 but prevent the movement from the moving member 3a side. Thus, the opening/closing operation of the stopper 1b closing the aperture for discharging the toner from the toner container 1 is surely performed with good operability and the stopper 1b is prevented from dropping. |
