摘要： By setting elements within the range that predetermined conditions are satisfied, for example, so that a size of a rotating polygon mirror is minimized, the rotating polygon mirror is made compact while the eclipse of light beams in the main scanning direction is prevented. The cost reduction of an apparatus is thus realized. The compact rotating polygon mirror reduces the consumption energy and the amount of heat generated in its drive system. Deteriorations in various optical characteristics including an increase in spot diameter of the light beam by temperature variation, uneven scanning pitch, and sub-scanning direction variation in beam pitch are suppressed.

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.
