发明名称 Image forming apparatus and image forming method using selective exposure and removal of liquid developer
摘要 In an image forming apparatus, a supply roller 4 supplies a liquid developer to the photo-conductive substance of a photosensitive drum or belt prior to an electrostatic latent image forming process. The supply roller 4 is applied with a voltage dentical in polarity with the charge of toner in the liquid developer, and the liquid developer is uniformly supplied to the surface of a photo-conductive substance to form a liquid developer layer. An exposure unit 6 selectively exposes the photo-conductive substance from the upside of the liquid developer layer in accordance with the image information, to thereby weaken an adhesion of the toner in an exposed area of the liquid developer to the photo-conductive substance. A removing roller 8 is applied with a voltage opposite in polarity to the toner charge to attract and recover the toner weakened in the adhesion by an electric field. The developed image caused by the liquid developer which has remained on the surface of the photo-conductive substance without being recovered is transferred to a recording medium 11 by a transfer roller 13.
