摘要： An optical scanning apparatus includes a light source; and a rotational polygon mirror having N reflecting surfaces, the rotational polygon mirror being configured to reflect a light flux emitted from the light source so that a scanning surface is scanned along a main-scanning direction with reflected from the rotational polygon mirror. A width of the light flux incident on the rotational polygon mirror in a direction corresponding to the main-scanning direction is smaller than a width of each reflecting surface of the rotational polygon mirror in the direction corresponding to the main-scanning direction.

摘要： An optical scanning unit includes a rotatable multi-faceted mirror having a plurality of faces reflecting light flux emitted from a light source to scan a scanning area in a main scanning direction. A width of the light flux striking the rotatable multi-faceted mirror is smaller than a length of a face of the rotatable multi-faceted mirror. The entire of light flux striking the rotatable multi-faceted mirror is reflected at a first face when the light flux reflected by the rotatable multi-faceted mirror is directed to the center portion of the scanning area. A part of the light flux striking the rotatable multi-faceted mirror is reflected at the first face while the remaining of the light flux is reflected at a second face when the light flux reflected by the rotatable multi-faceted mirror is directed to a least one of the two end portions of the scanning area.

摘要： An optical scanning device includes an optical housing in which a polygon mirror that is rotated by a motor is accommodated and an air inlet that includes a filter. An airflow guiding member is arranged at a position opposite to a surface of the polygon mirror on the air inlet side. An air inducing path is provided, which includes a first flowing path and a second flowing path. The first flowing path includes a first end linked to the air inlet and a second end arranged close to a mirror surface of the polygon mirror. The second flowing path is formed with a surface of the airflow guiding member on an opposite side of the air inlet and a top surface of the polygon mirror.

摘要： An optical scanning device includes plural light sources, a light deflector including a deflecting-reflecting surface, and a scanning optical system including plural folding mirrors and plural scanning lenses, wherein the plural scanning lenses have the same shape, at least one of an optical surface at the incidence side and an optical surface at the emission side has an asymmetric shape with respect to a sub-scanning direction, and has an asymmetric shape in the sub-scanning direction with respect to the main scanning direction, and a difference in a number of folding mirrors disposed between the corresponding scanning lens and the light deflector between light incident on the light deflector from a direction inclined to one side relative to a virtual surface including a normal line of the deflecting-reflecting surface and light incident on the light deflector from a direction inclined to the other side is an odd number.

摘要： A line-imaging lens condenses a light beam from a light-source unit in one direction to form a line image. An optical deflecting unit deflects the light beam passing through the line-imaging lens. An imaging optical unit images the light beam deflected by the optical deflecting unit in a spot shape on a scanning surface to be scanned. An adjusting unit adjusts a position of irradiation of the light beam from the light-source unit on the optical deflecting unit.
