An image forming apparatus includes a first air flow channel that has an air inlet, an exhaust outlet and filters. As air in the image forming apparatus is externally discharged along the first air flow channel, byproducts generated in the image forming apparatus are removed by the filters. The image forming apparatus also includes a second air flow channel, which also has an air inlet, an exhaust outlet and a filter for removing byproducts. With this configuration, the byproducts generated in the image forming apparatus can be re-collected.
