Abstract: An optical scanning device includes a cylindrical aperture, a support member, and a base portion. In the aperture, an opening portion restricts a beam path width of a laser beam emitted from a light source. The support member includes a cylinder supporting portion that pivotably supports the aperture. To the base portion, the support member is fixed by adhesion fixing. The base portion includes a pass-through portion that passes through between front and rear surfaces of the base portion and allows the support member to move in direction perpendicular to a pivoting axis of the aperture. The support member has a length such that its lower end portion projects from a rear surface of the base portion in the state where the support member has been inserted in the pass-through portion to such a position where laser beam is incident in the opening portion of the aperture.

Abstract: An angle formed between a first beam light ray D1 and a second beam light ray D2 is θ12, an angle formed between the second beam light ray D2 and a third beam light ray D3 is θ23, and an angle formed between the third beam light ray D3 and a fourth beam light ray D4 is θ34, where the first, second, third, and fourth beam light rays D1, D2, D3, and D4 have been reflected by a reflective surface of a rotating polygon mirror, θ23 is the smallest, of the three angles, that is, θ12, θ23, and θ34.
