The invention claimed is: 1. A powder container for use in an image forming apparatus, the powder container comprising: a container body configured to store a powder; a seal member disposed in a first end of the container body, the seal member positionable to permit and prohibit removal of the powder from the container body, the seal member allowing gas to flow into the container and powder to flow out of the container when the powder container is mounted in the image forming apparatus, and prohibiting the powder from flowing out of the powder container, when the powder container is removed from the image forming apparatus; and a filter member disposed opposite the seal member in a second end of the container body, the filter member configured to permit a gas to flow out of the container body. 2. The powder container according to claim 1, wherein the seal member is disposed in a bottom end of the container body, and the filter member is disposed in a top end of the container body. 3. The powder container according to claim 2, wherein the seal member comprises a valve configured to receive the gas to agitate the powder in the container body. 4. The powder container according to claim 3, wherein the valve is configured to receive the gas through a nozzle inserted into an opening in the valve. 5. The powder container according to claim 1, wherein the filter member is configured to permit air to flow into and out of the container body. 6. The powder container according to claim 5, wherein the filter member is disposed in an upper wall of the container body opposite a lower end in which the seal member is disposed, and the upper wall is substantially planar. 7. An image forming apparatus, comprising: a powder container comprising a container body configured to store powder, a seal member disposed in a first end of the container body, the seal member positionable to permit and prohibit removal of the powder from the container body, the seal member allowing gas to flow into the container and powder to flow out of the container when the powder container is mounted in the image forming apparatus, and prohibiting the powder from flowing out of the powder container, when the powder container is removed from the image forming apparatus, and a filter member disposed opposite the seal member in a second end of the container body, the filter member configured to permit a gas to flow into and out of the container body, and a nozzle configured to be disposed into an opening in the seal member, the nozzle configured to introduce the gas into the container body. 8. The image forming apparatus according to claim 7, further comprising: a gas source configured to deliver the gas through the nozzle into the container body to agitate the powder stored in the container body. 9. The image forming apparatus according to claim 8, wherein the gas source comprises an air pump. 10. The image forming apparatus according to claim 9, wherein the seal member is disposed in a bottom end of the container body, and the filter member is disposed in a top end of the container body. 11. The image forming apparatus according to claim 7, wherein the filter member is configured to permit air to flow into and out of the container body. 12. The image forming apparatus according to claim 11, wherein the filter member is disposed in an upper wall of the container body opposite a lower end in which the seal member is disposed, and the upper wall is substantially planar. 13. An image forming apparatus, comprising: a powder container comprising means for storing powder, means for permitting and prohibiting removal of the powder therethrough from the means for storing, and means for permitting a gas to flow therethrough into and out of the means for storing and for prohibiting the powder from flowing therethrough, and means for introduce the gas into the means for storing, wherein the means for introducing the gas comprises a pump device configured to pump the gas into the means for storing, and wherein the means for permitting and prohibiting removal comprises a seal member disposed in a bottom end of the means for storing, the seal member allowing gas to flow into the container and powder to flow out of the container when the powder container is mounted in the image forming apparatus, and prohibiting the powder from flowing out of the powder container, when the powder container is removed from the image forming apparatus, and the means for permitting the gas to flow comprises a filter member disposed in a top end of the means for storing. 14. The image forming apparatus according to claim 13, wherein the filter member is disposed in an upper wall of the means for storing opposite a lower end in which the means for permitting and prohibiting removal is disposed, and the upper wall is substantially planar.
