Abstract: An optical scanning device includes a light source, a deflector, an incident optical system and one scanning lens. The scanning lens includes a first face and a second face. In a main scanning direction cross section of the scanning lens, when a scanning range is separated, with on axis as a reference, into an image height region of a first direction and an image height region of a second direction that is opposite to the first direction, the incident optical system is disposed on a side of the image height region of the first direction. Curvature of the first face in a sub scanning direction cross section decreases from on axis toward off axis in the main scanning direction, and curvature of the second face in the sub scanning direction cross section increases from off axis of the first direction toward the second direction in the main scanning direction.

Abstract: An optical scanning device includes a light source which emits a light beam, a deflector, an incident optical system and one scanning lens. The deflector reflects and then deflects/scans the light beam emitted from the light source. The scanning lens includes a first face facing the deflector and a second face on an opposite side to the first face, and performs imaging of the deflected/scanned light beam on a surface to be scanned. When a curvature radius of the first face in a main scanning direction cross section is R1, a curvature radius of the second face in a main scanning direction cross section is R2, a lens thickness in an optical axis direction at a center of the scanning lens in the main scanning direction is d, and a refractive index of the scanning lens is n, following Formula (1) and Formula (2) are satisfied: 0 R2−R1>−(n−1)d/n (2).
