PROBLEM TO BE SOLVED: To provide a supply container for developer that is not vertically installed by a user and can be held at an accurate position in a main body of an image forming apparatus.SOLUTION: A developer supply container 1 includes a holding part that is non-rotationally held when the developer supply container 1 is attached to a main body of an image forming apparatus 100 and includes a discharge port 7d1 through which a developer T can be discharged and a pump member 6 that can change the internal volume inside the developer supply container 1. A tip part 9b that forms an end face, which is substantially perpendicular to the rotation axis of the developer supply container 1, of a protective member 9 constituting the holding part has a first convex part 9c1 and second convex part 9c2 that are arranged to be opposite to each other in the vertical direction across the rotation center P of the developer supply container 1, and a first concave part 9d1 and second concave part 9d2 that are arranged to be opposite to each other in the horizontal direction across the rotation center P of the developer supply container 1 to hold the position of the developer supply container 1 in the main body of the image forming apparatus 100. |
