1. A drying unit for a liquid electrophotographic printing apparatus equipped in the printing apparatus comprising a developing unit that develops an image on a photosensitive medium using a liquid carrier as a mediator and a transfer unit that transcribes the developed image on a printing paper, so that the liquid carrier remaining on the photosensitive medium can be dried, and a drying unit comprising:

  • a manifold having at least one inlet which is positioned near the photosensitive medium with a face opposite to the photosensitive medium open and through which hot air flows in, and at least one outlet through which a carrier evaporated from the photosensitive medium by the hot air flowing in is discharged;

    an inlet-outlet channel connecting the inlet to the outlet;

    a gas flowing means by which a gas in the manifold is discharged through the outlet and by which gas flows in the manifold through the inlet;

    a condenser that is positioned on the inlet-outlet channel and that condenses the evaporated carrier discharged through the outlet; and

    a heater that is located on the inlet-outlet channel and that heats the gas flowing in the manifold through the inlet.
