Abstract
A fine particle recovery device for recovering fine particles such as waste toner accumulating at a plurality of locations such as a photoreceptor and a transferring belt in an image forming apparatus. The fine particle recovery device possesses transport path, constituted by waste toner recovery pipes, which allows the waste toner from the plurality of locations to pass therethrough; a waste toner recovery container, attached to the exit of the transport path, which stores the waste toner in one lot; and auger axes, installed inside the transport path, which convey the waste toner toward the waste toner recovery container. Further, among transport distances from the respective locations to the waste toner recovery container, the transport distance from the location having the most waste toner to the waste toner recovery container is set to be the shortest.
