A vapor control system and an electrophotographic system having a vapor control system for reducing vapor emissions. A vapor collection mechanism collects at least some of the vaporized carrier which is then transmitted to a container having a vapor inlet and a vapor outlet containing a cooling liquid, the cooling liquid having a temperature less than the temperature of the vaporized carrier but greater than zero degrees Centigrade. A vapor inlet located at a point below the surface of the cooling liquid results in the vaporized liquid bubbling through the cooling liquid and being condensed therein. The cooling liquid is immiscible with water and, preferably is the carrier liquid. Mechanical resistance devices promote increased bubble residence time and smaller bubble size.
