Abstract
An oxidation catalyst unit for a wet-type electrophotographic image forming apparatus which filters a vapor produced at a fusing unit and a method thereof are provided. The oxidation catalyst unit and method includes a duct for guiding the carrier vapor produced at the fusing unit into the oxidation catalyst unit, a heater for heating the carrier vapor being guided along the duct, an oxidation catalyst carrying medium disposed behind the heater for catalyzing an oxidation reaction of the carrier vapor guided along the duct, and an absorbent filter for preventing entry of the carrier vapor into the oxidation catalyst in the form of liquid drops.
