Claim:
A powder container comprising: a body; and a pair of walls that block one end in a longitudinal direction of the body and the other end of the body, respectively, the powder container accommodating powder therein and being mounted in an apparatus that uses the powder, wherein the body has an opening in a location closer to the one end of the body to supply the powder within the powder container to the apparatus, wherein the powder container further includes: a shutter that is situated in a closed location to block the opening before the powder container is mounted in the apparatus and is moved along an outer peripheral surface of the body to an opened location to open the opening in a state where the powder container is mounted in the apparatus, a guide portion that maintains the shutter on the body and guides a movement of the shutter, and a boss that is positioned in a location between the shutter and an outer wall surface of the one of walls in the longitudinal direction of the body and next to the end of the shutter disposed in the closed location in a movement direction of the shutter, and protrudes outward in a radial direction from a center line of the body in the longitudinal direction, wherein the shutter receives an action from a movable member of the apparatus to open the opening in a state where the powder container is mounted in the apparatus, and wherein the boss contacts with the movable member of the apparatus when the shutter moves from the closed location to the opened location by the movement of the movable member after the powder container is mounted in the apparatus and blocks a further movement of the movable member in a direction where the shutter is further opened.
