Abstract
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 includes an exhaust guide forming a movement path of air so that the air moves from places around the topping corona devices to the outside of the printer, a filter for filtering impurity contained in the air passing through the exhaust guide, and an induction pump for allowing air to flow from the places around the topping corona devices to the filter through the exhaust guide. The ozone generated around the topping corona devices can be removed, thereby preventing the environment surrounding the printer from being contaminated by the ozone.
