Abstract: An optical scanning device includes a light source, a deflector, and a plurality of scanning lenses. A scanning lens lying closest to the deflector has a positive refractive power and the incident surface of it allows the oblique angle θ of the light beam entering the incident surface to vary from a center to an end of the incident surface. The incident surface satisfies the following conditions, where Δθ is the amount of change and dθ is the rate of change in the oblique angle θ of the light beam in the main scanning direction, d2θ is the rate of change in dθ, and Δ2θ is the amount of change in Δθ: d2θ

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.
