ABSTRACT:
A multibeam scanning device includes a deflecting system that deflects a plurality of beams, which are emitted by a light source, in a main scanning direction. On a first imaging optical system, the dynamically deflected beams are incident. A plurality of optical path deflection units deflect the optical paths of the optical beams passed through the first imaging optical system, respectively. Each of the plurality of optical path deflection units is capable of varying the deflection direction of the beam in the auxiliary scanning direction. A plurality of second imaging optical systems converge the beams deflected by the deflection units on target surfaces, respectively. A position adjusting system is provided to adjust a position of each of the second imaging optical systems so that the positional relationship of the second imaging optical system with respect to the beam incident thereon is maintained.
