Description of the Related Art An electrophotographic image forming apparatus is provided with a plurality of heat generating parts such as a power supply unit, a fixing unit, a writing unit and the like. For the purpose of cooling these heat generating portions, an electric fan or the like is used to discharge the residual heat inside the machine to the outside. However, the discharged air has a high temperature and is often accompanied by an offensive odor emitted from the transfer paper or toner, which gives a person near the air outlet an unpleasant feeling. In order to deal with such a defect, in many devices, it is general to arrange the exhaust port on the rear surface or the lower surface of the device. When there is a risk that the ventilation outlet will be located on the side due to restrictions such as the installation of peripherals, and there is a risk of causing discomfort to nearby people, measures such as setting the direction of the louver parts downward or backward are taken. In many cases.
