PROBLEM TO BE SOLVED: To provide an image forming device capable of reusing recovered developer whose color is obtained by the mixing of color developers through a color image formation process. SOLUTION: Into one place via a developing-liquid recovery piping 44, the image forming device collects and recovers, as recovered developing-liquids, residual developing-liquids whose colors are mixed after they are removed from the surfaces of corresponding photoreceptors by corresponding cleaning blades, 11, 12, 13, 14, and 15. It then actively mixes their colors deliberately. Thus, after the recovered developers whose colors are mixed are recovered into the one place, the mixture is supplied to a recycling development unit K by a developing-liquid adjustment device 46 as recycled developer 65, which is different in color from developer used in the color image formation process, and it is reused. Thus, the recycled developing-liquid can sufficiently be utilized as the developer for copying an internal or personal notice or document as in the reuse of the back of a used envelope as memo paper. |
