PURPOSE:To easily and surely execute the sealing and opening of a container and also the replenishment of toner without scattering the toner at the time of replenishing the toner by providing an opening/closing means for opening/ closing the opening part of a toner discharge port and a stirring means having a rotary shaft, one of whose ends passes through the container, and capable of stirring the toner in the container from the outside of the container. CONSTITUTION:The opening part 23 is made to face downward at the time of replenishing the toner. And when a knob 21 is pulled upward, a toner valve 25 is separated from a seat 26, and the toner drops through a gap by gravity. Furthermore, when the knob 21 is rotated, or rocked, a stirring blade 20 fixed on the rotary shaft 17 is rotated, or rocked, and then, the toner in the container main body 11 is stirred, and the flow property of the toner is increased, so that it is easy for the toner to flow out. And when the knob 21 is released after the toner in the container main body 11 is discharged and the replenishment of the toner is completed, the toner valve 25 is press-contacted with the seat 26 so as to close the opening part 23, so that the replenishing work can be finished without dropping the toner remaining in the container main body 11. |
