Abstract
An image forming apparatus includes a heat source, e.g., a lamp or a printed circuit board, and a fixing unit. A flow of air is circulated by a fan in a housing of the image forming apparatus. A cooling face of a cooling mechanism contacts the flow of air so that the flow of air is cooled. During the circulation of air, air cools the heat source. The cooling mechanism emits heat out of the image forming apparatus in response to cooling, without admitting air from outside of the apparatus.
