To suppress a load due to drive transmitted from a container gear while making the delivery performance of powder from a powder storage container to a powder conveyance device excellent.SOLUTION: A powder storage container is attached with a powder storage container 32 storing powder for image formation, and includes: a powder reception port which receives powder from the powder storage container; a body-side gear which transmits driving force to the powder storage container 32; a container reception part; an opening 33a which is provided on one end of the container body 33 storing the powder for the image formation; a conveyance tube reception member 330 which is arranged in an opening and can receive a conveyance tube; conveyance means; and a container-side gear 306 which is provided in the vicinity of the opening and can drive the conveyance means by being engaged with the body-side gear. The container-side gear 306 is arranged so as to be engaged with the body-side gear at an opening 33a side in a longitudinal direction of the container body with respect to the powder reception port. The opening 33a can be fitted into the container reception part.SELECTED DRAWING: Figure 29 【課題】粉体収容容器から粉体搬送装置の粉体の受け渡し性能を良好にしつつ、容器ギアから伝達される駆動による負荷を抑制する。【解決手段】画像形成用の粉体が収容された粉体収容容器３２が装着され、粉体収容容器から粉体を受け入れる粉体受入口と、駆動力を粉体収容容器３２に伝達する本体側歯車と、容器受入部を備えた粉体収容容器において、画像形成用の粉体を収容する容器本体３３の一端に設けられた開口部３３ａと、開口部に配置され、搬送管を受け入れ可能な搬送管受入部材３３０と、搬送手段と、開口部の近傍に設けられ、本体側歯車に噛合して前記搬送手段を駆動可能な容器側歯車３０６とを備え、前記容器側歯車３０６は、前記粉体受入口よりも前記容器本体の長手方向において前記開口部３３ａ側で前記本体側歯車と噛合可能に配置し、開口部３３ａは、容器受入部に嵌合可能とした。【選択図】図２９
