    Abstract: This light source unit includes a light source, a collimator lens, a support body, and an adhesive agent. The collimator lens is configured to collimate laser light emitted from the light source. In the support body, a first support portion configured to support the light source and a second support portion configured to support the collimator lens are integrally molded with each other by use of a synthetic resin. The adhesive agent is attached by a larger amount between the second support portion and a second face which is on an opposite side to a first face on the light source side of the collimator lens, than between the second support portion and the first face.

    Abstract: An optical scanning device includes a light source, a scanning member, a converging lens, a first aperture, a second aperture, and a support member. The first aperture is provided between the converging lens and the scanning member and includes a first opening portion configured to restrict a beam path width in a main scanning direction of the laser beams emitted from the light source. The second aperture is provided between the light source and the converging lens and includes a second opening portion and a cylindrical portion. The second opening portion is configured to restrict a beam path width in a sub scanning direction of the laser beams emitted from the light source, and is formed in the cylindrical portion. The support member includes a cylinder supporting portion that pivotably supports the cylindrical portion of the second aperture.

    Abstract: A laser scanning unit includes a light source portion, a scanning portion, a first correction portion, and a second correction portion. The light source portion outputs a plurality of light beams. The scanning portion scans the plurality of light beams to form a plurality of electrostatic latent images, respectively corresponding to a plurality of colors including at least one reference color and at least one non-reference color, in an image forming portion. The first correction portion applies an external mechanical force to an optical element located in a path of a reference beam, corresponding to the reference color, among the plurality of light beams to correct distortion of a scan line of the reference beam. The second correction portion controls the light source portion to correct distortion of a scan line of a non-reference beam, corresponding to the non-reference color, among the plurality of light beams.

    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 first aperture and an adjustment mechanism. The first aperture includes a first opening portion and a first cut portion. The first opening portion restricts a beam path width of a laser beam emitted from a light source. A first blocking member that blocks the laser beam is inserted in a detachable manner in the first cut portion in a direction perpendicular to a longitudinal direction of the first opening portion, at a predetermined position of the first cut portion. The adjustment mechanism is configured to adjust a fixed state of the first aperture.
