ABSTRACT:
A multi-optical beam scanning apparatus for scanning by a plurality of optical beams has a synchronization detector 6 including light receiving sensors 7a and 7b having light receiving surfaces juxtaposed in a main scanning direction of the plurality of optical beams. Synchronization of write timings in the main scanning direction of the plurality of beams is detected on the basis of signals obtained from the light receiving sensors 7a and 7b under a predetermined condition, so that accuracy of the synchronization detection is improved and the synchronization adjustment is facilitated.
