A powder container includes a containing portion that has an opening; a first opening/closing member that is movable between a first open position at which the opening is open and a first closed position at which the opening is closed; and a second opening/closing member that is movable between a second closed position at which the second opening/closing member covers an outside of the first opening/closing member and a second open position at which the first opening/closing member is exposed, wherein a direction in which the second opening/closing member moves from the second open position to the second closed position is different from a direction in which the first opening/closing member moves from the first open position to the first closed position, and wherein the second opening/closing member contacts the first opening/closing member and pushes the first opening/closing member into the first closing position when the second/closing member moves.
