Carrier vapor cleaner, a wet type electrophotographic image forming apparatus having the same, and a carrier vapor cleaning method

A wet type electrophotographic image forming apparatus comprising:

• a main body;
• a printing engine provided in the main body, and comprising a developing unit for attaching a developer liquid containing an ink and a carrier onto an image bearing body, and a transfer unit for transferring the developer liquid of the image bearing body onto a printing medium;
• a fusing part for fixing the transferred developer liquid onto the printing medium with heat and pressure;
• and
• a cleaning apparatus for removing an ozone and a carrier vapor being generated from the printing engine and the fusing part, the cleaning apparatus comprising:
• a duct for guiding a fluid to the outside, the fluid containing an ozone and a carrier vapor which are respectively generated from the fusing part and the printing engine,
• a fan for forcibly discharging the fluid through the duct,
• a carrier vapor combustion unit for burning a high concentration of carrier vapor of the fusing part inside the duct and accordingly lowering the concentration and increasing the temperature of the carrier vapor of the fluid which is circulated by the fan, and
• an oxidation catalyst body for increasing a rate of the oxidation of the fluid which is heated by the combustion unit, wherein said carrier vapor combustion unit comprises an igniter for sparking the carrier vapor.
