Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of improving the controlling performance of a liquid surface, and transferable even by a small electric field by adopting a material in a mesh shape, instead of a gravure plate. SOLUTION: A developer holding roller 3 holds a liquid developer 4 in a large number of penetrating fine pores 3a. A reverse electrostatic latent image 21 of the desired image is formed by electrifying the surface of a photoreceptor 2 with an electrifying device, and by selectively exposing with a selectively exposing device. By the contact rotation of the developer holding roller 3 with the photoreceptor drum 2, among the liquid developer 4 held in the fine pores 3a, the liquid developer 4 adjacent to the area where the electrostatic charge is present on the reverse electrostatic latent image 21, is attracted by the electrostatic force thereof, left stuck on the surface of the photoreceptor drum 2, and removed from the developer holding roller 3.  Subsequently, a recording paper 5 is brought into contact with the developer holding roller 3, and the final image is transferred on the recording paper 5.
