Oxidation catalyst unit, a controlling method thereof, and a wet-type electrophotographic image forming apparatus comprising the oxidation catalyst unit

A wet-type electrophotographic image forming apparatus comprising:

• a photoconductive medium;
• a laser scanning unit for scanning a laser beam onto the photoconductive medium;
• a developing unit for developing a developer on the photoconductive medium;
• a transfer unit for transferring the developer on the photoconductive medium to a recording medium;
• a fusing unit for fixing the developer on the recording medium;
• and
• an oxidation catalyst unit for oxidizing and resolving a carrier vapor generated in the fusing unit,
• wherein the oxidation catalyst unit comprises:
• a duct connected to the fusing unit to guide the carrier vapor generated in the fusing unit into the oxidation catalyst unit;
• a suction fan for guiding the carrier vapor into the duct;
• a heater for heating the carrier vapor;
• a cooling fan for cooling an inner temperature of the oxidation catalyst unit;
• and
• a controller for varying a velocity of the suction fan and the cooling fan, and a temperature of the heater according to data,
• wherein the data consists of at least one of an amount of image data, a temperature measurement, and a humidity measurement, and at least one of the velocity of the section fan and the temperature of the heater.
