To provide a powder storage container and a powder supply device that can prevent a powdery material from accumulating inside an opening coating part and prevent defective discharge of the powdery material, and an image forming apparatus.SOLUTION: A powder storage container 32 comprises: a powder storage part 33 that is formed with an opening 11 and stores therein a powdery material; conveying means 331 that conveys the powdery material inside the powder storage part toward the opening; and an opening coating part 34 that is attached to the powder storage part 33 to cover the opening 11, and the powder storage container has a discharge port W that discharges a powdery material discharged from the opening 11 to the inside of the opening coating part 34 to the outside. The power storage container includes a deformable member 42 that is fixed to the opening coating part 34 and in contact with the powdery material located between the opening 11 and the discharge port W, and has a contact/separation member 45 that performs an operation to contact and elastically deform the deformable member 42 and an operation to separate from the deformable member.SELECTED DRAWING: Figure 1 【課題】開口被覆部の内側で粉体物が滞留することを抑制でき、粉体物の排出不良を抑制できる粉体収納容器、粉体補給装置及び画像形成装置を提供する。【解決手段】開口部１１が形成され、内部に粉体物を収納する粉体収納部３３と、粉体収納部の内部の粉体物を開口部に向けて搬送する搬送手段３３１と、開口部１１を覆うように粉体収納部３３に取り付けた開口被覆部３４とを備え、開口部１１から開口被覆部３４の内側に排出された粉体物を外部に排出する排出口Ｗを有する粉体収納容器３２において、開口被覆部３４に固定され、開口部１１から排出口Ｗまでの間に位置する粉体物に接触する変形可能部材４２を備え、変形可能部材４２に接触して弾性変形させる動作と、離間する動作とを行う接離部材４５を有することを特徴とするものである。【選択図】図１
