Image formation apparatus using a liquid developing agent

Abstract

A multi-color image formation apparatus that has multiple developed image formation devices, each corresponding to one color. Each of the developed image formation devices has a photosensitive member, charging apparatus that charges the photosensitive member, exposure apparatus that exposes the charged photosensitive member, and developing apparatus that supplies highly viscous and highly concentrated color liquid developing agent to the surface of the latent image on the photosensitive member. Each of the developed image formation devices is provided with transfer apparatus that sequentially transfers the developed images, each of which has been formed on the surface of the latent imgae on one of the photosensitive members, to the paper transported by the transfer belt and thereby forms a color image on the paper. An electrostatic latent image is formed on a photosensitive member such that a developed image corresponding to the desired print image remains on the developing agent bearing member. The highly viscous and highly concentrated liquid developing agent that has been applied to the developing belt is removed at the positions corresponding to the electrostatic latent image and the normal developed image remaining on the developing belt is transferred to the paper the developed image is not spread during pressure transfer and the surface energy of the image bearing member is lower than that of the thin layer of liquid developer agent
