PURPOSE:To obtain a light beam scanning device having structure that the deterioration of image quality is restrained by making the rigidity of a mirror for converting an optical path high so that vibration resistance is improved without affecting the plane accuracy of the mirror for converting the optical path and the positional accuracy at a setting part. CONSTITUTION:This device is provided with a light beam generating means 1, a means 3 which deflects a light beam from the means 1 in a fixed direction so as to scan, a means 4 for forming the light beam which is deflected to scan into an image at a position on nearly one line, and a light beam reflecting means 13 which is positioned between the means 3 and an image forming position through the means 4 and constitutes an optical path conversion part. As to the light beam scanning device having the structure that the respective means are attached to individual holding parts and the holding parts are fixed to an attaching base member, a light reflecting member 13A is integrally resin- molded with its holding part 13B in the light beam reflecting means 13. |
