Abstract: A two-dimensional array include N light-emitting arrays each formed of M light-emitting units arranged equally spaced along a direction T tilting from a main scanning direction at an angle α toward a sub-scanning direction. The light-emitting arrays are equally spaced in the sub-scanning direction. A space ds2 between light-emitting arrays with respect to the sub-scanning direction satisfies ds2=ds1×M where ds1 is a positional difference in the sub-scanning direction between light-emitting units which are adjacent each other in the main scanning direction and orthographically-projected on a virtual line extending in the sub-scanning direction. The angle α satisfies α=sin−1((ds2/d1)/M) where d1 is a space between light-emitting units in the light-emitting array with respect to the direction T. The space ds2 is equal to the space d1.

In the image display apparatus, the two scanning lines have two different phases for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively. In the image display apparatus, the two scanning lines have two different starting points for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively.

Abstract: A scanning unit in an image forming apparatus includes a light source, a coupling lens, an aperture, an image forming lens, and a polygon mirror. The light source includes a plurality of surface-emitting lasers. The coupling lens, the aperture, and the image forming lens are arranged on the optical path of light beams emitted by the light source. The polygon mirror deflects light beams of an image formed by the coupling lens towards a photosensitive drum for scanning. The focal length of the image forming lens in a sub-scanning direction is set to be equal to or smaller than an optical path length between the image forming lens and the aperture.
