Summary:PROBLEM TO BE SOLVED: To provide a developer storing unit capable of discharging developer well from a deformable and flexible container.SOLUTION: A developer storing unit 25 includes: a flexible storing member 34 which has an opening 35a to store developer T; and a pressing member 21 which is rotatably supported at a position facing the storing member 34, for pressing the storing member 34. The pressing member 21 includes: a rotational shaft 60 which has a recess J that recesses toward a rotational center O; a pressing sheet 21b attached to the rotational shaft 60; and a sealing member 19 which seals the opening 35a and is released from the storing member 34 as the rotational shaft 60 rotates. Relating to the recess J, when pressing the storing member 34 by the pressing sheet 21b, the sealing member 19 enters the recess J so that a space V is formed between the sealing member 19 and the opening 35a. 【課題】 変形可能な可撓性容器から現像剤を良好に排出することができる現像剤収納ユニットを提供する。【解決手段】 開口３５ａを有し、可撓性を有し、現像剤Ｔを収納可能な収納部材３４と、収納部材３４に対向する位置で回転可能に支持され、収納部材３４を押圧する押圧部材２１と、を備え、押圧部材２１は、回転中心Ｏに向かって凹む凹部Ｊを有する回転軸６０と、回転軸６０に取付けられる押圧シート２１ｂと、開口３５ａを封止して回転軸６０が回転するに従って収納部材３４から剥離される封止部材１９と、を有し、凹部Ｊは、押圧シート２１ｂで収納部材３４を押圧する際に、凹部Ｊの中に封止部材１９が入り込むことにより封止部材１９と開口３５ａとの間に空間Ｖを形成する現像剤収納ユニット２５を構成した。【選択図】 図５
