Abstract
An image forming apparatus includes: an image formation section, a fan, a filter, a contamination detection section, an exhaust path, a circulation path, an air amount adjustment section, and a control section. The fan suctions and exhausts air at surroundings of the image formation section. The filter permits the air exhausted by the fan to pass through the filter. The contamination detection section detects a contamination level of the air which has passed through the filter. The exhaust path discharges the air to an outside. The circulation path returns the air towards a suction side of the fan. The air amount adjustment section increases and decreases an amount of the air flowing through the exhaust path and an amount of the air flowing through the circulation path oppositely to each other. The control section controls the air amount adjustment section in accordance with the contamination level of the air.
