    Abstract: A laser scanning unit includes a light source, a deflector, and a scanning lens. A surface shape of the scanning lens is formed so as to have: non-uniform-speed scanning characteristics in which a scanning speed with the light beam is the lowest at the one end and the other end of the to-be-scanned surface and is highest at a midpoint between the one end and the other end; and image formation characteristics in which a beam diameter of the light beam is largest at the one end and the other end of the to-be-scanned surface and is the smallest at the midpoint between the one end and the other end. The non-uniform-speed scanning characteristics and the image formation characteristics are characteristics in which a peak value of an intensity distribution of the light beam at each image height is made equal to each other by a combination of both characteristics.

    Abstract: An optical scanning device includes a cylindrical aperture, a support member, and a base portion. In the aperture, an opening portion restricts a beam path width of a laser beam emitted from a light source. The support member includes a cylinder supporting portion that pivotably supports the aperture. To the base portion, the support member is fixed by adhesion fixing. The base portion includes a pass-through portion that passes through between front and rear surfaces of the base portion and allows the support member to move in direction perpendicular to a pivoting axis of the aperture. The support member has a length such that its lower end portion projects from a rear surface of the base portion in the state where the support member has been inserted in the pass-through portion to such a position where laser beam is incident in the opening portion of the aperture.

    Abstract: n optical scanning device includes a scanning member, a plurality of light sources, a first reflection mirror, and a second reflection mirror. The scanning member scans incident laser beams in a predetermined main scanning direction. The plurality of light sources emit the laser beams from positions that are different along a sub scanning direction that is perpendicular to an optical axis direction of the laser beams and the main scanning direction. The first reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams emitted from the light sources. The second reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams reflected by the first reflection mirror toward the scanning member.

    Abstract: An optical scanner includes a multi beam light source, a scanning optical system, and a controller. The controller specifies selected beams, and changes light quantities of the respective selected beams at the same change timing based on the same profile data at respective positions in the main scanning direction which are fixedly determined as light quantity change positions. When the position of a center region in an arrangement width of the plurality of selected beams is moved in the main scanning direction in response to a selected mode of the beams, in the profile data, the controller derives a shift light quantity at a position shifted in the main scanning direction by an amount corresponding to the movement of the position of the center region, and the light quantity is modified so that the shift light quantity is used at the light quantity change position.
