ABSTRACT:
An oxidation catalyst device for a wet-type electrophotographic image forming apparatus and method of controlling the same are provided. The oxidation catalyst device includes a duct for guiding air inside a fixation device to the outside of the fixation device. The oxidation catalyst device further includes a fan for forcibly discharging the air inside of the fixation device, a heater for heating the air discharged from the fixation device, and an oxidation catalyst device-carrying body for facilitating oxidation resolution reaction of the carrier vapors entrained in the discharged air. The fan is driven at a first rotational speed of N1, during which the oxidation catalyst carrying body is warmed up, and a second rotational speed of N2, during which carrier vapors are heated and resolved.
