Each of the pressing out rollers provided in a stage next to a first pressing out roller has grooves formed at the opposite end portions thereof such that liquid developer which tends to be pressed out from the opposite ends of each of the second pressing out rollers is collected in the grooves. A pair of wiper blades having a length greater than the longitudinal ranges of the pair of pressing out rollers are disposed for being pressed against the outer peripheries of the pair of pressing out rollers including inner faces of the annular grooves at the opposite ends on the outer peripheries of the pair of pressing out rollers.
