Abstract
An image forming apparatus includes a light source, an optical deflector, an optical deflector casing, a bearing, and a sound absorption unit. The optical deflector reflects and deflects an optical beam emitted from the light source, having a rotational reflection member disposed on a rotation shaft to perform optical scanning. The optical deflector casing seals a space in which the optical deflector. The bearing rotatably supports the rotation shaft of the rotational reflection member with respect to the optical deflector casing, and includes at least portion exposed to an external space outside the sealed space of the optical deflector casing. The sound absorption unit is disposed opposite the exposed portion of the bearing with the external space therebetween.
