PROBLEM TO BE SOLVED: To suppress the positional deviation of a semiconductor laser and the variation in the radiation position of a scanning line due to the self heat release of the semiconductor laser and the heat release of a laser driving IC or the like. SOLUTION: The supporting structure of the semiconductor laser is constituted so that the engagement part of the semiconductor laser and a supporting member is protruded and a rib for causing air to flow into the engagement part is formed.
