Abstract
An image forming apparatus having front and rear surfaces, a photoreceptor having a rotation axis extending in a first direction, an exposure unit, and a cooling unit. The exposure unit includes a substrate having a longitudinal axis extending in the first direction, a first surface and a second surface. A plurality of light emitting elements that emit light toward the photoreceptor are mounted on the first surface of the substrate. The cooling unit includes an intake port that sucks air from outside of the image forming apparatus. The intake port is disposed at an intake port distance in the first direction to the rear surface. The intake port distance is shorter than a distance in the first direction of a center of the substrate to the rear surface. The cooling unit cools the substrate by blowing air sucked by the intake port onto the second surface of the substrate.
