PROBLEM TO BE SOLVED: To improve developer stirring and conveying properties by a rotary stirring member, while making the rigidity of a flexible blade member lower.SOLUTION: A developer storage container includes a rotary stirring member 53 rotated to convey a developer G stored in a container body 51 to a discharge port 51a, while stirring the developer G, inside. The rotary stirring member includes a rotary support member 55 rotated integrally with a rotary shaft 54 and flexible blade members 56 and 57 including at least one part thereof disposed on the rotation free end sides 55a and 55b of the rotary support member and sliding on the inner wall 51b of the container body, to convey the developer G to the discharge port 51a. The flexible blade members are attached to attachment surfaces 55A1 and 55B1 located on the upstream side in the rotational direction of the rotary support member. |
