Abstract: A toner container attachable to and detachable from a main body of an image forming device and including: a first chamber containing toner; a second chamber adjacent to the first chamber through a partition wall and downstream of the first chamber in a toner supply direction; and a switching member in the second chamber that is movable or rotatable and has a shell structure. The partition wall has a first aperture. A bottom wall of the second chamber opposing the partition wall has a second aperture and sits on the main body. The shell has third and fourth apertures. The fourth aperture coincides with the second aperture when the third aperture coincides with the first aperture, and the first aperture is closed by the shell when the third aperture faces an inner wall surface of the second chamber.

Abstract: An air flow sensor includes a case, a to-be-detected object, and a detector. The case includes an intake port and an exit port through which air is to flow. The to-be-detected object is located at a first position in the case when the air flowing from the intake port to the exit port has lower than a predetermined level of pressure, and is movable from the first position receiving the air when the air has equal to or higher than the predetermined level of pressure. The detector is disposed outside the case and is configured to detect a movement of the to-be-detected object and output an electrical signal.

Abstract: An option device for an electrical appliance of the invention is provided with a filter for purifying exhaust air from the electrical appliance, and an electric fan, wherein the air flow resistance in an external air inlet port formed independently of a suction port for sucking exhaust air from the electrical appliance is adjustable. According to this configuration, it is easy to secure balance between the exhaust air flow rate of the electrical appliance and the suction force by the electric fan without variably controlling the rotational speed of the electric fan.
