    (54) Wet type image forming apparatus


    (57) A wet type image forming apparatus comprises: a photo-sensitive drum (1) on which a latent image is formed and developed into a toner image with liquid-phase toner; an intermediate transferring medium (5) onto which the toner image is transferred; a pressurizing roll (8) which abuts a recording sheet (9) against the intermediate transferring medium (5) to transfer the toner image onto the recording sheet; means for reducing the potential of the toner image transferred onto the intermediate transferring medium; and means (20) for applying a mold releasing agent to the intermediate transferring medium (5) before the toner image is transferred from the image bearer (1) onto the intermediate transferring medium (5), whereby an image high in picture quality can be printed on a recording sheet (9) independently of the smoothness of the recording sheet, and transferring of the toner image can be achieved with low transferring voltage.
