ABSTRACT:
An optical scanning apparatus is provided, in which the optical scanning apparatus includes: a light source emitting an optical beam; an optical deflection unit deflecting the optical beam emitted from the light source; a scanning optical arrangement scanning a scanned surface by the optical beam in a main scanning direction; and an optical beam detection unit detecting the optical beam moving in the main scanning direction. The optical beam detection unit includes a first photodetector and a second photodetector, and the first photodetector including a first part and a second part that are electrically connected, wherein a first gap is formed between an edge of the first part and a first edge of the second photodetector, a second gap is formed between an edge of the second part and a second edge of the second photodetector, and the first gap and the second gap are not parallel to each other.
