置。[Claims for Utility Model Registration] (1) A housing provided with a laser light source, a polygon mirror that scans the laser light from the laser light source, and a lens system that guides the laser light from the polygon mirror to the photoreceptor; a synchronization detection mirror disposed outside the image forming area on the photoreceptor and reflecting the laser light emitted from the housing; and a laser beam from the synchronization detection mirror for guiding the laser to a synchronization detector that outputs a synchronization signal for image formation. and a light-receiving member that receives light, the synchronization detection mirror being provided in a separate part from the housing, and the light-receiving member being integrally attached to the housing. Device. (2) The synchronization detection mirror is approximately 2 of the optical path length from the laser beam emission position of the housing to the photoreceptor.
2. The optical writing device according to claim 1, wherein the optical writing device is disposed at a position with a distance of 1/2.
