Abstract
In an optical scanning device, a first deflector rotates about a first axis in a first direction and deflects light to scan the deflected light, and a second deflector rotates about a second axis parallel to the first axis in a second direction opposite to the first direction and deflects light to scan the deflected light. The light detecting unit detects the light deflected by the first deflector and the light deflected by the second deflector. As viewed in an axial direction along the first and second axes, the light detecting unit is disposed on one side relative to a first line and between second and third lines, the first line passing through the first and second axes, the second line passing through the first axis and being perpendicular to the first line, and the third line passing through the second axis and being perpendicular to the first line.
