DEVELOPER STORAGE CONTAINER, DEVELOPER SUPPLY DEVICE, AND IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To provide a developer storage container configured such that its capacity after use can be reduced, occurrence of impact force and impact noise is prevented even if a developer storage container long in a horizontal direction is set horizontally in a device body, and developer in the container can flow out of the container stably until the developer is completely used up. SOLUTION: The developer storage container 11, in which a horizontal length is formed so as to be greater than a vertical length and which has flexibility and stores developer therein, has a suction passage 15, which extends on the side of a container underside 1A from a side surface 11C located in a lengthwise direction to a side surface 11D located on the opposite side to this and in which one end 15A can communicate with a suction means 12 for sucking and conveying developer to a developing device 4. In the suction passage 15, a plurality of suction holes 16 communicating with the inside of the container are formed over the entire area of the container in the lengthwise direction.
