PURPOSE:To prevent the developing of image parts preceeding the second developing and the formation of photographic fogs in nonimage parts in the stage of the second and subsequent developing by providing plural sets of combinations of electrostatic recording heads and wet type developing devices along the conveying route of a recording body and providing destaticizers respectively between these combinations. CONSTITUTION:Electrostatic latent images of the 1st time are formed on recording paper 5 by a recording head 1a, and are developed to a color A by a developing device 6a, after which the images are destaticized in a destaticizer 7a so that the surface potential of the paper 5 is made uniformly around 0 level. The electrostatic latent images of the 2nd time are formed on the paper 5 removed the irregularity in the surface potential thereof in such a way by the next recording head 1b and the latent images are developed to a color B by a developing device 6b, whereby the images of the color B are superposed on the images of the color A. After the paper 5 is destaticized by a destaticizer 7b, the electrostatic latent images of the 3rd time are formed by the next developing device 6c. |
