摘要

PROBLEM TO BE SOLVED: To provide a developer storage container capable of preventing damage and deformation of an abutting part for preventing erroneous attachment and a developing device and an image forming apparatus equipped with the same.SOLUTION: A container projection part 85 is provided protrusively on the lower surface of a toner container 900. The container projection part 85 has a plurality of abutting parts A1 to A5. In addition, the plurality of abutting parts are continuously connected by wall parts 110 to 118. An image forming apparatus body to which the toner container 900 is properly mounted is provided with a plurality of parts to be abutted having the same arrangement pattern as the arrangement pattern of the abutting parts A1 to A5. Even if the toner container 900 is erroneously inserted into the image forming apparatus body on which a part to be abutted having an arrangement pattern different from the arrangement pattern of the abutting parts A1 to A5 is disposed, the abutting parts A1 to A5 are prevented from being damaged and deformed by the wall parts 110 to 118.
