Claim Text:
1. An optical scanning device comprising: a light source configured to emit a plurality of laser beams; a scanning member configured to deflect and scan the laser beams emitted from the light source; a converging lens configured to converge the laser beams emitted from the light source, on a deflection surface of the scanning member; a first aperture provided between the converging lens and the scanning member and including 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; a second aperture provided between the light source and the converging lens and including a second opening portion and a cylindrical portion, the second opening portion being configured to restrict a beam path width in a sub scanning direction of the laser beams emitted from the light source and being formed in the cylindrical portion; and a support member including a cylinder supporting portion that pivotably supports the cylindrical portion of the second aperture, further comprising: a first base portion to which the first aperture is fixed by adhesion fixing; and a second base portion to which the support member is fixed by adhesion fixing, wherein the first base portion includes a first pass-through portion that is formed to pass through between a front surface and a rear surface of the first base portion and allows the first aperture to move in the main scanning direction, and the second base portion includes a second pass-through portion that is formed to pass through between a front surface and a rear surface of the second base portion and allows the support member to move in the sub scanning direction.
