Abstract: PROBLEM TO BE SOLVED: To provide a developing device capable of preventing the surface staining of the non-image part of a latent image carrier without using a pre-wetting device for coating the latent image carrier with a pre-wetting liquid in order to prevent the surface staining of the non-image part of the latent image carrier, and an image forming device using the developing device. SOLUTION: The surface of a two-layer forming roller 43 is uniformly coated with developer 18 by a coating roller 44 at a developer coating part C. The thin layer of the developer 18 on the roller 43 is carried to a developer transfer part A and formed to two layers, that is, a carrier liquid layer 18b and a toner particle layer 18a by two-layer forming bias. The developer 18 formed to the two layers advances to a developing part B so that carrier liquid comes into contact with the surface of a photoreceptor 10Y first. Thus, the surface of the photoreceptor 10Y is covered with the carrier liquid in the developer 18 and the toner particles in the developer 18 carried on a developing roller 42 do not directly come into contact with the non- image part of the photoreceptor 10Y.  Therefore, the toner particles are completely prevented from adhering to the non-image part of the photoreceptor 10Y without using the pre-wetting device, so that the surface staining of the non-image part is prevented from occurring.
