Abstract
An image forming apparatus has: a housing; a member to be cooled provided inside the housing, the member to be cooled in which heat builds up; an airflow producing portion provided in a predetermined position of the housing for taking in air outside the housing; an air guide member for passing the air thus taken in through a hollow cross-section part, and guiding the air to the member to be cooled to cool the member to be cooled; an air inlet portion provided at one end of the air guide member for taking in the air from the airflow producing portion; and an air blowoff portion provided at another end of the air guide member for sending the air to the member to be cooled, the air blowoff portion in which the cross-sectional area of the hollow cross-section part is smaller than the cross-sectional area of the hollow cross-section part in the air inlet portion.
