Abstract: A liquid developer imaging system including a cartridge (150) for containing developing solution; a developing container (140) for receiving developing solution supplied from the cartridge; a developing roller (110) installed to be rotated facing a photosensitive object, and partly submerged in the developing solution contained in the developing container; and a metering blade (160) for scraping off developing solution coated on the surface of the developing roller to a predetermined thickness. A developing supply structure can be considerably simplified because a high-density developing solution is directly used in developing an image without a process of diluting the solution, and an image can be developed to have high definition because the concentration of developing solution coated on the developing roller (110) is regularly controlled by a metering blade (160).

Abstract: PURPOSE: A wet type electrophotographic image forming apparatus is provided to remove an air gap between a transfer backup roller and a transfer belt to enable stabilized image transfer. CONSTITUTION: A wet type electrophotographic image forming apparatus provides a developer to an electrostatic image formed on a photosensitive drum(130) to form a toner image and transfers the toner image to a transfer belt(110), and then transfers the toner image to a recording medium and fixes the toner image on the recording medium. The image forming apparatus includes a transfer backup roller(160) to which transfer bias is applied to transfer the toner image to the transfer belt. The transfer belt and transfer backup roller come into contact with each other in a direction opposite to a running direction of the transfer belt on the basis of a line(L) connecting the center of the photosensitive drum and the center of the transfer backup roller.

Abstract: PURPOSE: A wet type image forming device is provided to allow a separated liquid carrier to flow along a toner image transferred by a transfer medium, thereby preventing the density of the toner image led to a transfer roller from being changed. CONSTITUTION: At least one photo-receptor(130) on which an electrostatic latent image is formed is provided. At least one developing unit(140) develops the electrostatic latent image with a developer to form a toner image. A transcriber receives the toner image from the photo-receptor(130) to transfer the received toner image to a recording medium. The transcriber comprises a transfer medium(110) receiving the toner image from the photo-receptor(130) and traveling a track toward the recording medium by being sloped downward in a traveling direction, and a transfer backup roller(160) facing with the photo-receptor(130) by interposing the transfer medium(110) therebetween, wherein a line connecting the photo-receptor(130) and a center of the transfer backup roller(160) is vertical to a surface of the transfer medium(110).
