Summary:PROBLEM TO BE SOLVED: To provide a developer replenishment container that prevents toner from clogging in an exhaust passage of toner and can charge a toner storage bag with an appropriate amount of air.SOLUTION: A developer replenishment container 40 includes a developer storage bag 41 that is included in a container frame body, has elastic restoring force, and accommodates developer, and a developer exhaust passage 42 for exhausting the developer accommodated in the developer storage bag to the outside of the developer replenishment container, where the container frame body and developer storage bag have a space therebetween to constitute an airtight chamber 44. The developer replenishment container 40 further includes negative pressure maintaining and releasing means capable of maintaining and releasing a negative pressure state in which the developer storage bag is shrunk due to the elastic restoring force of the developer storage bag and thereby the pressure in the airtight chamber becomes lower than the pressure outside the developer replenishment container, and information output means for outputting information on at least one of the amount of developer accommodated in the developer storage bag and the size of the developer storage bag. 【課題】トナーの排出路のトナーの詰まり等を防止するとともに、トナー収容袋に適切な量の空気の充填を可能とする現像剤補給容器を提供する。【解決手段】容器枠体に内包され、弾性復元力を有し、現像剤を収容する現像剤収容袋４１と、現像剤収容袋に収容されている現像剤を現像剤補給容器の外部へ排出するための現像剤排出路４２とを具備し、容器枠体と現像剤収容袋との間の空間は気密室４４を構成し、現像剤補給容器４０は、現像剤収容袋の弾性復元力により現像剤収容袋が収縮することにより気密室の気圧が現像剤補給容器の外部の気圧よりも低い負圧状態の維持及び解除が可能な負圧維持解除手段と、現像剤収容袋に収容されている現像剤の量及び現像剤収容袋の大きさのうち少なくとも一方の情報を外部に出力する情報出力手段とを具備する。【選択図】図３
