Title: Image forming apparatus capable of producing a high-precision light beam with a simple structure

Abstract: An image forming apparatus includes an image carrier and an optical scanning device. The optical scanning device generates an optical scanning beam and includes an enclosure. The enclosure includes a pair of arch-like-shaped supporting members. Inside the enclosure there are provided a light source for emitting a light beam, a light deflector for deflecting the light beam emitted from the light source so as to convert the light beam into the optical scanning beam, and at least one reflecting mirror for reflecting the optical scanning beam deflected by the light deflector to scan the image carrying surface of the image carrier. At least one of the reflecting mirrors includes a specific reflecting mirror having a light reflecting surface and mounted on the pair of arch-like-shaped supporting members at a position to reflect the optical scanning beam with the light reflecting surface toward the image carrying surface of the image carrier.
