Abstract:
1. A developer container comprising: a containing portion that is capable of containing a developer therein, the containing portion having an opening through which the developer passes; a first opening/closing member that is supported by the containing portion so as to be movable between a first open position at which the opening is open and a first closed position at which the first opening/closing member closes the opening; and a second opening/closing member that is supported by the containing portion so as to be movable between a second closed position at which the second opening/closing member doubly closes the opening by covering an outside of the first opening/closing member and a second open position at which the first opening/closing member is exposed to the outside, wherein the second opening/closing member rotates by an operation of inserting the developer container in an image forming apparatus without performing an operation of rotating the container portion, wherein the first opening/closing member is supported so as to be movable in an installation direction, which is a direction in which the developer container is removably installed into the image forming apparatus, wherein the second opening/closing member is supported so as to be movable in a circumferential direction centered around the installation direction, and wherein the second opening/closing member includes an opening/closing contact portion that contacts an opening/closing contacted portion provided to the image forming apparatus, the opening/closing contacted portion extending in a spiral shape with respect to the installation direction, moves the second opening/closing member from the second closed position to the second open position as the developer container moves in the installation direction, and moves the second opening/closing member from the second open position to the second closed position as the developer container moves in a removal direction, which is a direction in which the developer container is removed from the image forming apparatus.
