<P>PROBLEM TO BE SOLVED: To obtain a developer container which is equipped with an outer case having a cross section formed of a circular-arc part and a rectangular part, and an inner case capable of turning along the inner surface of the circular-arc part, and constituted so that a discharge port formed at the circular-arc part is covered with a sealing member disposed in the inner case, and which can solve a problem that there is a possibility that a stored toner is leaked because the discharge port is opened to the outside when the rectangular part is strongly gripped or hit to apply an external load to the outer surface of the rectangular part. <P>SOLUTION: The developer container has: the outer case 40 having the circular-arc part 42 where a lower discharge port 44 for discharging a developer is formed on a peripheral wall, and the rectangular part 41 which has connection parts 40a and 40b formed like plates, and an outer wall formed between the respective connection parts; and the inner case 50 having a supply aperture 53 which can be opposed to the lower discharge port 44, and provided to be turnable in contact with the inner peripheral surface of the circular-arc part 42 so as to open and close the lower discharge port 44. The circular-arc angle θ1 of the circular-arc part 42 is set to 180° or larger. <P>COPYRIGHT: (C)2009,JPO&INPIT |
