Claim:
1. An optical scanning device comprising: a light source that emits optical beams; a deflection unit received in a casing, deflecting the optical beams emitted from the light source, and allowing the deflected optical beams to be scanned in a main scanning direction; an image forming lens fixed to a protruding seat part, which protrudes from a bottom wall part of the casing, by using an adhesive, and forming an image of the optical beams deflected and scanned by the deflection unit on a surface to be scanned at a constant velocity; and a temperature sensor that detects temperature of the image forming lens, wherein a concave portion is formed at an end surface of a protruding side of the protruding seat part to allow for receiving of the temperature sensor, and the adhesive is filled in the concave portion to fix the temperature sensor and is interposed between the end surface of the protruding side of the protruding seat part and the image forming lens to fix the image forming lens to the protruding seat part.
