Abstract
Provided are a light scanning unit and an electrophotographic image forming apparatus including the light scanning unit. The light scanning unit includes a light source, a polygonal mirror deflecting light emitted from the light source in a main scanning direction, an imaging lens transmitting the deflected light to a photoconductor for forming an image, and a synchronization detecting unit detecting a synchronization signal from the deflected light for synchronization in the main scanning direction. The light scanning unit has a total scanning rate, including a synchronization detecting optical path, ranging from about 60% to 75%.
