Abstract
An image forming apparatus includes an exhaust duct to guide air inside the image forming apparatus to an outside of the image forming apparatus. A positive ion generator emits a positive ion into the exhaust duct. A negative ion generator emits a negative ion into the exhaust duct. The negative ion generator is shifted from the positive ion generator in one of an air flow direction of the air moving inside the exhaust duct and a direction perpendicular to the air flow direction.
