学系。 In an optical device in which a light beam from a light source is made incident on an optical deflection device that deflects and scans the beam through a beam shaping optical system, the beam shaping optical system deflects the substantially parallel beam from the light source into at least one sheet at a time in the sub-scanning direction. A beam shaping optical system characterized in that a cylindrical lens having positive and negative refractive powers forms a line image in the vicinity of the deflection device.
