Air circulation system of liquid electrophotographic printer
 In an air circulation system of a liquid electrophotographic printer, an engine shell includes a developing unit for developing an electrostatic latent image which is formed on a photoreceptor belt and having an air injector, a drying unit for drying the developed image, and a transferring unit for transferring the developed image to print paper. Air in the engine shell is taken in and exhausted to the outside though a main path. A filter is installed on the main path for filtering air. A return path is branched from the main path and through which the air taken in from the engine shell is supplied to the air injector. An air pump provides a driving force such that air can flow along the main path and the return path. Thus, as air can be exhausted from the engine shell and the exhausted air can be re-supplied to the air injector using a single pump, the structure of the system is simplified.
