Abstract

A wet type electrophotographic image forming apparatus includes a photosensitive medium, a light exposure device, a developing device, a transfer device, a fuser device, an oxidation catalyst device, a temperature sensor, a power supply device and a control device. The oxidation catalyst device includes an oxidation catalyst carrying body and a heater, and removes vapor of developer solution from the fuser device by utilizing oxidation decomposition. The control device receives data about the temperature detected from the temperature sensor, and variably controls the temperature of the oxidation catalyst device in accordance operational modes such as warm-up mode, standby mode and print mode. Considering the fact that the oxidation catalyst device has higher efficiency at optimum activation temperature, appropriate temperature control can guarantee increased oxidation efficiency of the oxidation catalyst device.
