PURPOSE:To realize a wet developing device which can perform development with small amount of developer, where a stage for removing the excess developer so as to prevent the surface fogging of a non-image part need not be provided, and where an electrostatic latent image carrier and a developing roller arc easily restarted even when a contain a longer time elapses after forming the image. CONSTITUTION:This wet developing device 4 develops an electrostatic latent image on the electrostatic latent image carrier 1 with the developer 30, and is constituted of the developing roller 45 being a conductor or a conductor provided with a thin insulating layer as an outermost layer and having elasticity, and a potential applying means 90. Then, at the time of developing the electrostatic latent image, 1st potential is applied at standby time after finishing the development and 2nd potential is applied to the developing roller 45 from the potential applying means 90. The 1st potential is potential having a value between the surface potential of the high electrostatically charged area of the carrier 1 and the surface potential of a non electrostatically charged area or a low electrostatically charged area and the 2nd potential is potential having the same polarity as the electrostatically charged polarity of toner particles 31. |
