Abstract:
1. A liquid-development electrophotographic apparatus for forming on an image-bearing body a plurality of color images that are developed by a plurality of developing units, one for each color, that use liquid toner, comprising a carrier-removing unit for removing excessive carrier from a toner layer formed on said image-bearing body, wherein said carrier-removing unit includes two or more conductive or semiconductive collection rollers to which a bias voltage is applied in such a direction as to press toner against said image-bearing body and which are adapted to be brought into contact with said image-bearing body, an upstream one of said carrier-removing units with respect to the direction of progress of a developing process having said collection rollers being rotated in the same direction as the direction of surface movement of said image-bearing body whereas a downstream one of said carrier-removing units with respect to the direction of progress of the developing process having said collection rollers being rotated in the opposite direction, each of said collection rollers being equipped with carrier collecting means.
