Abstract:
1. An optical scanning apparatus comprising: a deflector, which deflects a laser beam emitted from a light source to scan the laser beam on a scanned surface; an optical element, which directs the laser beam deflected by said deflector to the scanned surface; a support member, which supports a vicinity of an end portion of said optical element in a longitudinal direction of said optical element; a pressure member, which cooperates with said support member to press said optical element on said support member, wherein a supporting point by said support member is fixed, and a pressure point by said pressure member is movable in the longitudinal direction; and an adjusting mechanism, which slidably adjusts a distance in the longitudinal direction between the supporting point by said support member and the pressure point by said pressure member by sliding the pressure point by said pressure member along the longitudinal direction of said optical element in a state in which said pressure member presses said optical element.
