Abstract

In one aspect, a carrier recovery apparatus of a liquid electrophotographic printer includes a drying unit, a cooling unit for cooling and condensing carrier vapor evaporated by the drying unit, a condenser for condensing the carrier vapor which has not been condensed by the cooling unit, and a carrier recovery container. In another aspect, a carrier recovery apparatus of a liquid electrophotographic printer includes a drying unit, a first cooling unit for cooling and condensing carrier vapor evaporated by the drying unit, a second cooling unit for cooling the carrier which has passed through the first cooling unit, a condenser for condensing the carrier vapor which has not been condensed by the first and second cooling units, and a carrier recovery container. Accordingly, the efficiency of condensing carrier vapor is improved. As a result, the recovery percentage of a carrier increases, and the duration of a filter is extended.
