Abstract
An image forming apparatus having: an inside-air duct having a first inlet to an inside of the image forming apparatus; a first ventilator provided in the inside-air duct; an outside-air duct having a second inlet to an outside of the image forming apparatus; a common duct into which the inside-air duct and the outside-air duct are merged; a second ventilator provided in at least one of the outside-air duct and the common duct; a filter provided in the common duct; and a control section that retrieves information indicative of an flow rate in the inside-air duct and increases a pressure produced by the second ventilator based on the retrieved information such that an flow rate in the outside-air duct is substantially constant with respect to an increase of the flow rate in the inside-air duct.
