ABSTRACT:
To provide an electrophotographic printer which can satisfy regulations for exhaust gas emission easily, a printer is provided with a circulation line for taking out and returning gas generated in a casing of the printer, and a heat exchanger, for cooling the gas and for recovering solvent, is provided midway on the circulation line. The heat exchanger lowers a concentration of the gas. A detection sensor detects a temperature and humidity of the gas in the casing and a heater, provided downstream of the heat exchanger, adjusts a humidity of the gas which is then returned into the casing, upon receiving an output of the detection sensor.
