Abstract
A wet-type electrophotography apparatus using a non-volatile, high-viscosity, high-concentration liquid toner as a liquid developer and having a photoconductive medium, a prewetting device applying a film of prewetting solution to the surface of the photoconductive medium, a developing roller feeding the liquid developer to the photoconductive medium while making contact with the photoconductive medium, and causing toner particles in the liquid developer to adhere to the photoconductive medium in accordance with a electric field formed between the developing roller and the photoconductive medium, so that a toner image formed on the photoconductive medium is transferred directly to a printing medium, or to a printing media via an intermediate transfer medium to obtain a printed image. The apparatus also has oil removal means making contact with the formed toner image surface to remove the excess prewetting solution and the excess carrier solution in the liquid toner from the toner image surface on either the photoconductive medium or the intermediate transfer medium.
