Patent ID: 6996352

Claim:
A gas exhausting apparatus for use in a wet electrophotographic image forming device, the apparatus comprising: an exhaust duct forming an air flow passage from an inside of a wet electrophotographic image forming device to an outside of the device; an exhaust fan inhaling air from the inside of the device through the exhaust duct and exhausting the air through the exhaust duct to the outside of the device; and an air purification unit that removes impurities included in the air inhaled by the exhaust fan through the exhaust duct, the air purification unit including a combustion part disposed so that at least a portion of the inhaled air comes into contact with the combustion part, wherein the exhaust duct includes: a first inhalation guide formed to inhale and guide impurity-containing high temperature air in the device and having the air purification unit disposed therein to pass the impurity-containing air through the air purification unit; a second inhalation guide formed to inhale and guide non-impurity-containing air of room temperature in the device; and an exhaust guide formed to communicate with the first inhalation guide and the second inhalation guide and having the exhaust fan disposed therein to mix the impurity-containing air and the non-impurity-containing air respectively inhaled through the first inhalation guide and the second inhalation guide and then exhaust the impurity-containing air and the non-impurity-containing air to the outside of the device.
