Abstract
A drying unit and method of drying for a liquid electrophotographic printing apparatus, the drying unit that is equipped in the printing apparatus comprising a developing unit that develops an image on an 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. The drying unit for the liquid electrophotographic printing apparatus is positioned near the photosensitive medium and includes a manifold having an inlet and an outlet; an inlet-outlet channel being between the inlet and the outlet and connecting them; a gas flowing unit by which the gas in the manifold is discharged through the outlet and gas flows in the manifold through the inlet; a condenser that condenses the evaporated carrier discharged through the outlet; and a heater that heats the gases flowing in the manifold through the inlet. Also, the liquid carrier drying method includes determining the injection condition; heating injection air according to the determined gas injection condition and evaporating the carrier on the photosensitive medium by injecting the…
