Abstract
An optical scanning apparatus includes a plate member, having a rotation axis and a reflection surface, that deflects and scans a laser beam emitted from a light source by performing reciprocating-rotation around the rotation axis, an actuator configured to drive the plate member, an fθ-lens configured to focus the laser beam deflected by the plate member on a surface of a photosensitive drum, and an optical box configured to house the plate member, the actuator, and the fθ-lens. The actuator is provided nearer to a side of the optical box toward which the laser beam is reflected by the reflection surface than the reflection surface of the plate member is.
