  • the above developer supply container has the following problems.
  • the first is that the gears that transmit the rotational driving force often slip when they cooperate with each other, which tends to cause the shutter member to be opened/closed, or the opening/closing is not in place;
  • Second the number of parts is large, resulting in many assembly steps and relatively high manufacturing costs.
  • the third is that during the transportation process, the limiting members are easily released indiscriminately, causing the container body to leak the developer.
  • the main object of the present invention is to provide a developer supply container which can directly rotate the shutter member to open/close the developer discharge port;
  • Another object of the present invention is to provide a developer supply container which can restrict the rotation of the shutter member in the direction of opening/closing the developer discharge opening by a simple structure
  • a developer supply container provided by the present invention includes a main body for accommodating a developer, a developer discharge port provided on the main body for discharging the developer, and a shutter member for opening and closing the developer discharge port.
  • the shutter member is provided with a grip portion.
  • the developer supply container may further include: a guide rail provided on one end surface of the main body, the rib provided at the grip portion of the shutter member, and the rib being abutted against the guide rail to restrict the rotation of the shutter member when the shutter member is rotated.
  • the guide rail is arc-shaped and coaxial with the shutter member.
  • the developer supply container further includes a stopper protrusion adjacent to the body end of the shutter member grip portion, and a locking member for preventing the shutter member from rotating, wherein the locking member includes one that is integral with the shutter member grip portion and is substantially closed along the shutter member An extending portion extending in a direction and a locking projection extending from the extending portion toward the main body for abutting against the stopper projection on the main body; two of the stopper projections.
