The powder container includes an operation device and a rotation portion to rotate with operation of the operation device. The rotation portion is configured to contact a wall of the image forming apparatus or the removable component in a state in which the rotation portion maintains a posture in a direction of attachment of the powder container to the image forming apparatus or the removable component and is rotatable together with an engagement portion, which is opposed to the wall, of the image forming apparatus or the removable component while engaging the engagement portion, without hindering the powder container from moving in the direction of attachment, to restrain the powder container from moving in a direction of detachment from the image forming apparatus or the removable component.
