Title: Optical scanning device and image forming apparatus

Abstract: An optical scanning device includes a light source, a deflector, and an optical system including an elongated optical element that focuses deflected luminous flux on a surface of a medium to be scanned. The optical element is supported by a first elastic member and reinforced by a reinforcing member arranged outside a beam effective range along a length of the optical element. The optical element is pressed by a pressing member in a pressing direction orthogonal to a deflection direction, and biased by a second elastic member in a direction opposite to the pressing direction. The pressing member and the second elastic member control a posture of the optical element at a substantially central part in a main scanning direction.
