Abstract
An optical writing apparatus includes a deflecting part having a deflection plane for deflecting a plurality of light beams, a synchronization detection mirror for reflecting the plurality of light beams from the deflecting part, a synchronization detection part for detecting the timing for deflecting the plural light beams reflected from the synchronization detection mirror, and a housing for housing the deflecting part and the synchronization detection part. The synchronization detection part includes a lens for converging the plural light beams reflected from the synchronization detection mirrors, a light detection plate for detecting the plural light beams converged by the lens, and a holding member for holding the lens and the light detection plate.
