Patent ID: 7920811

Claim:
A storage container comprising: a storage container main body that stores an image forming material therein; a flow-out opening that flows out the image forming material stored in the storage container main body; a shutter that is supported to be movable between an opening position, which opens the flow-out opening and a closing position, which closes the flow-out opening; a seal member that, in a case where the shutter is disposed at the closing position, is interposed between the flow-out opening and the shutter and is elastically deformed by the shutter in a thickness direction thereof along the flow-out direction of the image forming material so as to seal the flow-out opening; a restricting portion that is supported on the shutter; and an open-close movement restricting portion that, in a state where the shutter is moved to the closing position, is disposed at a position opposed to the restricting portion, and that, in a case where the shutter moved to the closing position is pressed from outside and the seal member is thereby elastically deformed further in the thickness direction, is disposed at a position overlapping with the leading end position of the restricting portion along a moving direction of the shutter and, in a case where no external force is applied to the shutter, is disposed at a position not overlapping with the leading end position of the restricting portion along the moving direction of the shutter.
