Abstract: A print material container comprising a body to hold print material, a housing, and a detecting member. The housing being coupled to the body and including a movable mass to move in the housing when a shaking force is applied to the print material container. The detecting member to detect the shaking force and to signal a feedback of the shaking force relative to a shaking force threshold.

Abstract: An image forming apparatus includes a development cartridge having a developing roller. The developing roller includes a roller body, and a shaft to pass through a central axis of the roller body. A coupling structure is disposed at an end part of the shaft, is movable from a first position to a second position, and includes a first coupling piece and a second coupling piece. Positions of the first coupling piece and the second coupling piece are maintained with respect to one another by a static frictional force between surfaces of the first coupling piece and the second coupling piece to hold the coupling structure in the first position. When a predetermined force overcomes the static frictional force, the first coupling piece and the second coupling piece disengage from one another to allow the coupling structure to move from the first position to the second position.

Abstract: A print material container comprising a body, a transfer mechanism, an inner connector, and an outer connecter. The transfer mechanism is to move print material in or out of the body. The inner connecter is on a connecting side of the body, and is to couple to a first location of an image forming apparatus to provide print material to the image forming apparatus. The outer connecter is on the connecting side of the body, and is to couple to a second location of the image forming apparatus to collect or receive unutilized print material transferred or received from the image forming apparatus.

Abstract: An example of a container is disclosed. The example disclosed herein comprises an impermeable container wall, a container releasing valve, and a gas vessel. The impermeable container wall defines the boundaries of an inner volume of the container. The container releasing valve is installed in the container wall to release gas from the inner volume of the container to the outside of the container. The gas vessel is installed in the inner volume of the container. The gas vessel comprises a gas vessel wall, a pressurized vessel gas, and a gas vessel releasing system. The gas vessel wall defines the boundaries of an inner volume of the gas vessel, wherein the gas vessel wall is impermeable and allows for a pressure difference between the inner volume of the gas vessel and an outer volume of the gas vessel. A pressurized vessel gas is enclosed within the inner volume of the gas vessel. And a gas releasing system is to release a certain quantity of the vessel gas to the inner volume of the gas container.
