Abstract
An opening/closing member is movable between an open position in which a passage opening through which developer passes is open and a closed position in which the passage opening is closed. The opening/closing member includes a protrusion that protrudes toward an edge of the passage opening with respect to a scrape limiting portion, the protrusion being disposed on each of two sides with respect to a direction that is perpendicular to directions of movement between the open position and the closed position. A front end of the opening/closing member in a closing direction from the open position to the closed position is disposed so as to be separated from a surface of the edge of the passage opening.
Claims10
An opening/closing member that is movable between an open position in which a passage opening through which developer passes is open and a closed position in which the passage opening is closed, the opening/closing member comprising:
- a protrusion that protrudes toward an edge of the passage opening with respect to a scrape limiting portion, the protrusion being disposed on each of two sides with respect to a direction that is perpendicular to directions of movement between the open position and the closed position,
- wherein a front end of the opening/closing member in a closing direction from the open position to the closed position is disposed so as to be separated from a surface of the edge of the passage opening.
A developer supplying apparatus comprising:
- a developer container vessel that includes a container that contains developer and an outlet through which the developer flows out from the container;
- an inlet that is connectable to the outlet and into which the developer flows from the outlet;
- an opening/closing member that is movable between an open position in which a passage opening through which developer passes is open and a closed position in which the passage opening is closed, the opening/closing member including a protrusion that protrudes toward an edge of the passage opening with respect to a scrape limiting portion, and the protrusion being disposed on each of two sides with respect to a direction that is perpendicular to directions of movement between the open position and the closed position, wherein a front end of the opening/closing member in a closing direction from the open position to the closed position is disposed so as to be separated from a surface of the edge of the passage opening;
- and
- a transport member that transports the developer that has flowed from the inlet.
