摘要： A powder container is for use with an image forming apparatus, and the image forming apparatus includes a driving protrusion that is rotatable and that protrudes toward an upstream side in an insertion direction in which the powder container is inserted. The powder container includes a container body to store powder, a cap attached to the container body, and a transmitted structure provided on the cap to contact the driving protrusion. The transmitted structure extends outward from an outer circumference of the powder container. The cap is rotatable relative to the container body in a predetermined angular range. The rotation of the cap relative to the container body is restricted so that the container body rotates along with the rotation of the cap when the rotation of the cap exceeds the predetermined angular range.
