Abstract:
1. An image forming device including an image support object which supports an electrostatic latent image, and a developing device which turns the electrostatic latent image formed on the surface of the image support object, into a visible image with toner, the image forming device comprising: a powder storing unit storing powder for image formation which is either a developing agent containing a toner and a carrier or a toner; and a powder supplying unit supplying the powder stored in the powder storing unit, to the developing device, the powder storing unit comprising: a gas supplying unit blowing off a gas from an exhaust outlet of the gas supplying unit into the powder storing unit; and a powder passage allowing the powder storing unit to communicate with the developing device, wherein the gas supply unit includes a jet generating part including a porous member which forms the exhaust outlet, and a gas supplying pump supplying gas to the jet generating part, the jet generating part being connected with the powder storing unit, wherein the image forming device comprises an intermediate powder storing part provided in the powder passage to temporarily store powder received from the powder storing unit, and a downstream powder transporting part provided in the powder passage to transport the powder stored in the intermediate powder storing part, to the developing device.
