Liquid electrophotographic printer having exhaust device

A liquid electrophotographic printer having topping corona devices for charging a photosensitive belt, a laser scanner for forming an electrostatic latent image on the charged photosensitive belt, and a development unit for developing the electrostatic latent image to an image having a predetermined color, the liquid electrophotographic printer comprising:

• an exhaust guide for the movement of air so that air moves firm an area near the topping corona devices to the outside of the printer;
• a filter for filtering impurity contained in the air moving through the exhaust guide;
• and
• an induction pump for pumping air through the exhaust guide, from the area near the topping corona devices to the filter,
• wherein the exhaust guide is a hollow path formed between a supporting frame for supporting the development unit and a rear frame on which the supporting frame is fixed, and wherein the supporting frame has throughholes for allowing air to move into the exhaust guide.
