PROBLEM TO BE SOLVED: To prevent positional relation between a light source and a lens from being changed due to deformation of a holder for holding the light source and the lens.SOLUTION: An optical scanner exposing a photoreceptor includes a light source for emitting light, a deflector for deflecting and scanning the light from the light source to guide it to the photoreceptor, a lens for guiding the light from the light source to the deflector, and a holder for holding the light source and the lens. The holder includes a first wall part for holding the light source, a second wall part for holding the lens, and a pair of third wall parts integrated with the first and second wall parts and holding an optical path located between the light source and the lens. |
