Abstract
A light-emitting diode exposure head includes a lens array, a long holder to hold the lens array, and a substrate having light-emitting diodes that emit light to expose a photosensitive member. The lens array includes lenses and condenses the light emitted from the light-emitting diodes on the photosensitive member. The long holder includes a base portion having an opening into which the lens array is inserted, and a pair of extended portions extended in a direction that is opposite of an emitting direction of the light along an optical axis of each of the lenses from both ends of the base portion in a transverse direction of the long holder. The pair of extended portions and the substrate are bonded in a state where leading edges of the pair of extended portions are in contact with a light-emitting surface of the substrate that serves as a surface of the substrate.
