An optical scanning device includes a polygon scanner that deflects and scans light beams, a body on which the polygon scanner directly mounted, and a heat dissipating unit that dissipates heat of the deflection scanning unit. The heat dissipating unit is located at a position on an outer surface of the body corresponding to the deflection scanning unit. The body is provided with a pair of wall portions on the outer surface. The wall portions face each other with the heat dissipating unit between them, and extend in a direction in which air blown by an air blowing unit flows to form an air-flow path.

Optical scanning device and image forming apparatus

An optical scanning device configured to irradiate an object with light generating from a light source via at least one mirror with a first end portion and second end portion which are attached to a housing and to scan the object with the irradiating light is provided, wherein the first end portion of the at least one mirror is movably supported by the housing and the second end portion of the at least one mirror is bonded to the housing.
