TONER STORAGE CONTAINER AND IMAGE FORMING APPARATUS

To provide a toner storage container that reduces a toner that is not discharged and remains.SOLUTION: A toner storage container 41Y is removably attached to an image forming apparatus, and comprises: a storage unit 411 that is formed with a discharge port 427 opening to the outside and stores toner; and a conveying member 421 that is arranged along a conveyance path of the toner and in which a rotation shaft provided at one end in the direction of the conveyance path is pivotally supported by the storage unit 411. The conveying member 421 has a coil-like shape wound spirally around a center line extending from the rotation shaft. An inner wall of the storage unit 411 includes an inclined plane 425 that intersects with the conveyance path of the toner. The outer diameter of a portion of the conveying member 421 corresponding to the inclined plane 425 is different from the outer diameter of the other portion.SELECTED DRAWING: Figure 5 【課題】排出されずに残存するトナーを少なくしたトナー収容容器を提供する。【解決手段】画像形成装置に着脱可能なトナー収容容器４１Ｙであって、外部に開放される排出口４２７が形成されており、トナーを収容する収容部４１１と、トナーの搬送経路に沿って配置され、搬送経路の方向の一端に設けられた回転軸が収容部４１１に軸支された搬送部材４２１と、を備え、搬送部材４２１は、回転軸から延びる中心線の周りに螺旋状に巻かれたコイル状の形状を有し、収容部４１１の内壁は、トナーの搬送経路と交わる傾斜面４２５を含み、搬送部材４２１は、傾斜面４２５に対応する部分の外径が他の部分の外径と異なる。【選択図】図５
