This optical scanning unit comprises a light source; an optical scanning mechanism for scanning with light from the light source; a start detecting mechanism for detecting scan light of the optical scanning mechanism at an end portion of a scanning range of the scan light to detect beginning of light scanning; and a frame which has a higher rigidity than that of a frame of an image forming apparatus and to which the light source, the optical scanning mechanism and the start detecting mechanism are attached. The image forming apparatus comprises an endless photosensitive body; charging unit for charging the photosensitive body; an optical scanning unit for exposing the photosensitive body to light, including a light source, an optical scanning mechanism having the same structure as the aforementioned optical scanning unit; a developing unit for developing an electrostatic latent image formed on the photosensitive body by light exposure by the optical scanning unit; and a transfer unit for transferring a toner image on the photosensitive body onto a sheet. Alteration of the optical path of the optical scanning unit by external force applied is made smaller by making the frame of the optical scanning unit more rigid than that of the image forming apparatus.
