ABSTRACT:
An optical apparatus comprises a first image bearing member; a second image bearing member; a first reflection member for reflecting a deflection-scanned first laser beam toward the first image bearing member; a second reflection member for reflecting a deflection-scanned second laser beam toward the second image bearing member; and a curving support member for curving, in a reflection direction, a reflection surface of the first reflection member, which reflects the first laser beam. The curving support member includes a support portion which supports a surface on the side of a direction in which the first reflection member curves, a contact portion of the support portion with respect to the first reflection member is of a shape having a curvature.
