    摘要： A surface-emitting laser array includes a plurality of light emitting parts arranged in a two-dimensional formation having two orthogonal directions. When the plurality of light emitting parts are orthogonally projected on a virtual line parallel to one of the two orthogonal directions, a spacing between two of the plurality of light emitting parts along the virtual line is equal to an integral multiple of a predetermined value. The plurality of light emitting parts include a first light emitting part, a second light emitting part adjacent to the first light emitting part, and a third light emitting part adjacent to the second light emitting part, and a spacing between the first and second light emitting parts differs from a spacing between the second and third light emitting parts.

    摘要： An optical axis of at least one surface of a resin-made diffracting lens is shifted in a main scanning direction with respect to an incident beam. A synchronous detection can cancel a problem of a misalignment in the main scanning direction due to a temperature variation. A light reflected from a second surface of the resin-made diffractive lens condenses on a position that is displaced in an optical axis direction from an optical beam outgoing point of a semiconductor laser, and thereby the light reflected again from the semiconductor laser does not form an image on a scanned surface and an impact on the image becomes low.
