Abstract

An optical scanning apparatus has: a deflection unit that scans beams emitted from a plurality of laser light sources; an imaging unit having one or more optical elements for imaging beams scanned by the deflection unit; and a supporting unit having a higher rigidity than a rigidity of the imaging unit. The supporting unit has a pair of receiving members that support the imaging unit, in a sub-scanning direction, near both ends, as seen in a main scanning direction, of the imaging unit. The optical scanning apparatus also has; a bend-adjustment unit that corrects bend. The bend-adjustment unit is disposed on the supporting unit at a plurality of positions along the main scanning direction. The optical scanning apparatus further has a free-sliding unit for securing free expansion of the imaging unit due to temperature changes thereof.
