Optical scanning device and image forming apparatus including the same

摘要

An optical scanning device includes a rotating polygon mirror, a motor, a substrate, a heat releasing member and a heat transfer member. The rotating polygon mirror deflection scans light emitting by a light source. The motor rotatively drives the rotating polygon mirror. The substrate has a drive circuit part for controlling the motor. The heat releasing member releases heat generated from the substrate. The heat transfer member is sandwiched between the substrate and the heat releasing member to be compressively deformed. A receiving portion that part of the heat transfer member compressively deformed enters is formed in a first part of the heat releasing member in which the heat transfer member is provided.
