Abstract
An optical scanner includes a light source that emits a light beam, a deflection unit that deflects the light beam, an optical unit that introduces the light beam to a target surface, a housing unit that stores these components, and a member that contacts the light source and/or the optical unit. The light source and/or the optical unit changes in attitude due to a temperature change while the optical scanner is operating. The member extends or contracts according to the temperature change so as to reduce the change of the attitude.
