Abstract
An image forming apparatus having; a fusing unit that heats and presses a recording medium with an image transferred thereto, thereby fixing the image thereon; a first duct section in which air that contains emissions generated by the fusing unit flows; an ion generation unit provided away from the first duct section to generate ions; a second duct section in which air that contains the ions generated by the ion generation unit flows; a third duct section connected to the first and second duct sections, such that air flows in from the first and second duct sections, whereby the emissions are charged by the ions; a filter unit provided in the third duct section to trap the charged emissions; and a blowing unit that generates air flows from the connections with the first and second duct sections in the third duct section toward the filter unit.
