Patent ID: 7301554

Claim:
A light scanning device comprising: an optical element that images, on an image holding body, a light beam emitted from a light source; a holding member that holds the optical element; scanning line curve correcting means for correcting the optical element in a sub scanning direction to correct a scanning line in the sub scanning direction, the scanning line being formed by the light beam; and scanning line inclination correcting means for entirely tilting the optical element around a supporting point positioned at a center of the optical element along the scanning line to correct an inclination of the scanning line, wherein the supporting point is positioned near an optical axis of the optical element and is in contact with a center of the holding member in a plane parallel to the scanning line and perpendicular to the optical axis of the optical element, wherein at least one part of the scanning line curve correcting means, and at least one part of the scanning line inclination correcting means are provided integrally with the holding member, wherein the holding member further includes a supporting member that is long in a main scanning direction, and that supports the optical element from the sub scanning direction, the holding member includes a reference surface that contacts with the optical element and provides a reference position for the optical element in the holding member, wherein the scanning line curve correcting means includes pressing means for pressing the optical element from an opposite side of a surface of the optical element that contacts with the supporting member, wherein the pressing means includes a pressing member that engages the optical element from the opposite side of the surface of the optical element that contacts with the supporting member, and a pressing operation member that pushes the pressing member against the optical element, and wherein the reference surface is formed at a position that does not correspond to a position where the pressing means presses the optical element.
