    摘要： A wet electrophotographic apparatus comprises a liquid toner developer having a nonvolatility, a high viscosity, and a high concentration, a photosensitive body (10) on which an electrostatic latent image is to be formed, a prewetting device (13) for applying a prewetting liquid film to the photosensitive body (10), a development roller (26) disposed in contact with the photosensitive body (10) and adapted for feeding the liquid developer to the photosensitive body (10) and for allowing toner particles of the liquid developer to adhere to the photosensitive body (10) by the action of the electric field produced between the development roller (26) and the photosensitive body (10), so as to transfer the toner image formed on the photosensitive body (10) to a printing medium directly or through an intermediate transfer body (15) and thereby to form an image, wherein the apparatus further comprises oil removing means (30 or 20) in contact with the surface of the formed toner image for removing excessive prewetting liquid and carrier liquid of the liquid toner from the surface of the toner image. Excessive prewetting liquid and carrier is prevented from being transported to the contact part where the photosensitive body is in contact with the intermediate transfer body, staying there, flowing, and damaging the image. Therefore, heating and melting of the toner layer is not influenced in fixing.

    摘要： A wet electrophotographic device using a nonvolatile, high-viscosity and high-concentration liquid toner as liquid developer, which is equipped with a photosensitive body (10) on which an electrostatic latent image is formed, a pre-wetting device (13) for coating the surface of the photosensitive body (10) with a pre-wetting liquid, a development device (14) in contact with the photosensitive body (10) for allowing toner particles to adhere to the photosensitive body (10) in accordance with an electric field generated between the development device (14) and the photosensitive body (10), an intermediate transfer body (15) onto which the toner particles adhering to the photosensitive body (10) are transferred, a press roller (19) which is turned in contact with the intermidiate transfer body (15) and conveys a printing medium while pressing the printing medium against the intermediate transfer body (15), and a heater (18) which heats part of the surface of the intermediate transfer body (15) at a position before the body (15) comes into contact with the press roller (19). With this constitution, the toner transferred onto the intermediate transfer body (15) can be efficiently fused without giving a thermal influence upon the photosensitive body (10).

    摘要： A wet electrophotography device using nonvolatile, high-viscosity and high-concentration liquid toner as liquid developer, which is equipped with a photosensitive body (10) on which an electrostatic latent image is formed, a pre-wetting device (13) for coating the surface of the photosensitive body (10) with a pre-wetting liquid, a development device (14) including a development roller, and a developer applying means for coating the development roller with the liquid developer. The development roller is in contact with the surface of the photosensitive body (10) to supply the liquid developer to the photosensitive body (10) and allow toner particles of the liquid developer to adhere to an image carrier in accordance with an electric field generated between the development roller and the photosensitive body (10). The developer applying means comprises a plurality of rollers in contact with each other to convey the supplied liquid developer while spreading and applying it onto the surfaces of the rollers successively. By applying a bias voltage to the final-stage roller which is pressed against the development roller, the surface of the final-stage roller is coated with the liquid developer in accordance with an electric field generated between the final-stage roller and the development roller by means of the bias voltage.
