Summary:PROBLEM TO BE SOLVED: To provide a developer storage container that includes a movable wall that can move, and has suppressed a developer from leaking to the upstream side in the direction of travel with respect to the movable wall, and an image forming apparatus including the same.SOLUTION: A toner container 30 includes a container body 37, a movable wall 32 (P1), a toner discharge port 377, and an inner wall seal 322. The toner container 30 supplies a toner to a developing device 20. The movable wall 32 conveys a toner while moving toward the toner discharge port 377 inside the container body 37. The inner wall seal 322 forms the outer peripheral part of the movable wall 32, and is compressed and deformed between an inner peripheral part of the container body 37 and the movable wall 32. The cross section of an internal space of the container body 37 is set to be reduced toward the final position of the movable wall 32.SELECTED DRAWING: Figure 15 【課題】移動可能な移動壁を備え、移動壁よりも移動方向上流側に現像剤が漏れることを抑制した現像剤収容容器、およびこれを備えた画像形成装置を提供する。【解決手段】トナーコンテナ３０は、コンテナ本体３７と、移動壁３２（Ｐ１）と、トナー排出口３７７と、内壁シール３２２と、を備える。トナーコンテナ３０は、現像装置２０にトナーを補給する。移動壁３２は、コンテナ本体３７の内部をトナー排出口３７７に向かって移動しながら、トナーを搬送する。内壁シール３２２は、移動壁３２の外周部を形成するとともに、コンテナ本体３７の内周部と移動壁３２との間で圧縮変形される。コンテナ本体３７の内部空間の断面積は、移動壁３２の最終位置に近づくにつれて小さくなるように設定されている。【選択図】図１５
