ABSTRACT:
This invention is an optical scanning apparatus comprises a plurality of beam generating units adapted to generate beams; an optical unit adapted to collimate axes of the beams generated by the plurality of beam generating units to scan at intervals corresponding to a recording direction along a image bearing member; a detection unit adapted to detect a beam interval between the plurality of beams collimated by the optical unit; a driving unit adapted to change the beam interval by driving the optical unit; a first control unit adapted to drive/control the driving unit so as to make the detected beam interval become a predetermined value; and a second control adapted to drive/control the driving unit in accordance with a rotation position of the image bearing member.
