Abstract
An image forming apparatus comprises a semiconductor laser for emitting laser light for irradiating a photosensitive drum, BD for detecting laser light before irradiating the photosensitive drum to output BD signal as a reference for determining an initiation position of the photosensitive drum, and a laser circuit board. The laser circuit board causes the semiconductor laser to emit laser light detected by the BD with first light amount. When a BD sensor outputs the BD signal, a laser circuit board causes the semiconductor laser to emit the laser light with second light amount.
