A developer cartridge, comprising: a developer container configured to sealingly contain developer therein, the developer container having an outlet through which the developer flows out of the developer container;a casing configured to accommodate the developer container therein, the casing supporting the developer container to allow the developer container to rotate about an axis thereof in a rotating direction;a sealing member configured to seal the outlet; anda drive input configured to transmit rotational driving force to the developer container;wherein the sealing member is fixed to an interior surface of the casing, the interior surface of the casing facing the developer container. 2. The developer cartridge according to claim 1, wherein the sealing member includes: a sealing portion configured to seal the outlet; andan attachment portion extending from a downstream end portion of the sealing portion with respect to the rotating direction of the developer container, the attachment portion being attached to a fixing portion of the casing. 3. The developer cartridge according to claim 2, wherein the sealing member is configured to elastically deform into a U-shape, andan outer surface of a portion of the U-shaped sealing member defining the sealing portion is attached to the developer container. 4. The developer cartridge according to claim 1, wherein the developer container has a circular shape when viewed along the axis of the developer container. 5. The developer cartridge according to claim 4, wherein the developer container has a radius equal to or greater than two-thirds of a shortest distance from the axis of the developer container to an inner wall surface of the casing. 6. The developer cartridge according to claim 1, wherein the developer container has a polygonal shape when viewed along the axis of the developer container. 7. The developer cartridge according to claim 1, wherein the developer container includes metal. 8. The developer cartridge according to claim 1, wherein the developer container includes resin. 9. The developer cartridge according to claim 1, wherein the developer container includes silica gel disposed therein. 10. The developer cartridge according to claim 1, wherein the sealing member has a sheet-like shape. 11. The developer cartridge according to claim 1, wherein the sealing member includes metal. 12. The developer cartridge according to claim 1, wherein the sealing member includes resin. 13. The developer cartridge according to claim 1, further comprising a rotating shaft, wherein the developer container includes a first wall at a first longitudinal end of the developer container and a second wall at a second longitudinal end of the developer container, the rotating shaft extending through both of the first and second walls. 14. The developer cartridge according to claim 1, wherein the sealing member includes an upstream end portion and a downstream end portion with respect to the rotating direction of the developer container, andwherein, as the developer container rotates in the rotating direction, the downstream end portion of the sealing member is separated from the developer container and the entire sealing member extends along the interior surface of the casing to which the upstream end portion of the sealing member is fixed. 15. A developer cartridge, comprising: a developer container configured to sealingly contain developer therein, the developer container having an outlet through which the developer flows out of the developer container;a casing configured to accommodate the developer container therein, the casing supporting the developer container to allow the developer container to rotate about an axis thereof in a rotating direction;a sealing member configured to seal the outlet, wherein the sealing member is fixed to the casing;a drive input configured to transmit rotational driving force to the developer container;a sealing portion configured to seal the outlet; andan attachment portion extending from a downstream end portion of the sealing portion with respect to the rotating direction of the developer container, the attachment portion being attached to a fixing portion of the casing,wherein the sealing portion is adhered to the developer container by a first adhesive, and the attachment portion is adhered to the fixing portion by a second adhesive, andwherein the second adhesive has an adhesive strength greater than the first adhesive. 16. The developer cartridge according to claim 15, wherein the attachment portion is fixedly adhered to the fixing portion by the second adhesive. 17. The developer cartridge according to claim 16, wherein: the sealing member has resilient restoring force, andthe sealing member is configured to elastically deform into a U-shape when the sealing portion is adhered to the developer container by the first adhesive, and configured to entirely extend straight after the sealing portion has been completely separated from the developer container. 18. The developer cartridge according to claim 17, wherein the sealing portion is configured to extend along and be adhered to an inner surface of the casing after the sealing portion has been completely separated from the developer container.
