An image forming apparatus includes: a photosensitive element; a charger for electrically charging the photosensitive element; an exposure device for scanning laser light across the photosensitive element that has been electrically charged by the charger; an exposure window positioned away from the exposure device for a predetermined distance and through which the laser light passes; and an exhaust fan for drawing air between the exposure device and the exposure window toward the charger and discharging the air from the image forming apparatus. The exposure window is defined by a plurality of walls, in which a first wall that is the farthest wall from the charger and a second wall that is the nearest wall from the charger satisfy a formula: A<B, where A is a distance between the first wall and the exposure device, and B is a distance between the second wall and the exposure device.
