Abstract
A scanning lens for an optical scanner includes a specific adjusting axis and a curved surface. The specific adjusting axis makes a rotating center of the scanning lens and center of the curved surface. The scanning lens is disposed on a holding member having a receiving surface, so that the curved surface is in contact with the receiving surface. A position of the scanning lens is adjusted by a rotating mechanism that rotates the scanning lens.
