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 including a light source and a rotating polygon mirror having a plurality of reflective surfaces scans a scan area of a surface in a main scanning direction with the light flux emitted from the light source and reflected by the rotating polygon mirror. All the light flux is reflected by a first reflective surface when light flux deflected by the rotating polygon mirror is directed onto a center position of the scan area, and a part of the light flux incident to the rotating polygon mirror is reflected by a second reflective surface adjacent to the first reflective surface when light flux reflected by the rotating polygon mirror is directed onto at least one end of both ends of the scan area and the light flux obliquely enters a plane perpendicular to a rotation axis of the rotating polygon mirror.
