Abstract
An electrophotographic apparatus is provided with a squeezer for removing unnecessary liquid from a liquid layer formed on a movable photosensitive medium between the step of developing an electrostatic latent image formed on the photosensitive drum by liquid developer and the step of fixing the toner image formed thereby on the photosensitive medium or transferring such toner image to a transfer medium. The apparatus is further provided with a non-contact squeeze power forming device such as a corona discharger or air knife for damming up the unnecessary liquid, and also provided with a liquid layer control member for contacting the liquid dammed up and bulged into a crest-like form so that the thickness of the liquid flowing down the surface of the photosensitive medium is uniform. At least a portion of the liquid-contacting surface of this member forms a planar or a convexly curved surface having a progressively increasing spacing with respect to the photosensitive medium in the direction opposite to the direction of movement of the photosensitive medium.
