Abstract
An image forming apparatus includes a first housing inside an image forming unit, a second housing that includes a fixing unit, a conveyance belt provided in the first housing to convey a sheet, first and second intake fans, and first and second duct units. The first intake fan takes in air to suction the sheet to an outer peripheral surface of the conveyance belt. The first duct unit provided in the first housing forms an air path for exhausting air from the first intake fan. The second intake fan provided in the second housing takes in air near the fixing unit. The second duct unit provided in the second housing passes air flowing in from the first duct unit and the air taken in by the second intake fan. The second duct unit includes an exhaust port for exhausting air outside and a filter through which the exhausted air passes.
