OPTICAL SCANNING DEVICE AND IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical scanning device such that vibration of a lens is reduced with simple constitution.SOLUTION: An optical scanning device includes: a lens 70 that has a lens portion 70g through which a light beam is transmitted and a support portion 70h on which the light beam is not incident at an end portion side; a bearing surface 72a that is provided to a bottom surface of a housing 105 and on which the lens 70 is placed; and a support portion that is molded integrally with the housing 105 for bonding the lens 70. The support portion includes: a second support bearing surface that is opposed to the support portion 70h of the lens 70 placed on the bearing surface 72a; and a slope shaped portion that is inclined from an end of the second support bearing surface positioned on a bottom surface side with respect to an apex of the lens 70 in a direction separating from the second support bearing surface and the bottom surface. The lens 70 placed on the bearing surface is fixed by an adhesive applied between the bearing surface and the lens and is fixed to the support portion by an adhesive between the slope shaped portion and the support portion 70h of the lens 70.
