ABSTRACT:
A laser scanning apparatus includes: a plurality of laser light sources including a first laser light source and a second laser light source; a scanner for scanning laser lights emitted from the plurality of laser light sources in a main scanning direction; a light receiving sensor for receiving the laser lights deflected and scanned by the scanner; and a signal generation unit for generating a first signal which is in synchronization with a pixel clock for the second laser light source based on an output from the light receiving sensor obtained by a laser light emitted from the first laser light source, and for generating a second signal which is in synchronization with a pixel clock for the first laser light source based on an output from the light receiving sensor obtained by a laser light emitted from the second laser light source.
