PROBLEM TO BE SOLVED: To provide an optical scanner device and an image forming apparatus that enable easy recycling of optical system components and a cost reduction.SOLUTION: An optical scanner including a light source, a collimator lens, an aperture, and a housing comprises an intermediate member 120 holding the collimator lens 52 and fixed to the housing by adhesion. The holding member has housing adhesion parts 123a and 123b, one of which is fixed to the housing by adhesion. An aperture member 130 is provided integrally with this intermediate member. In the aperture member, a light emission port 54a is arranged such that even in the case where one of the housing adhesion parts is fixed to the housing by adhesion, the light emission port forms the same shape. |
