ABSTRACT:
Each light detecting sensor, which is installed corresponding to each photoconductor drum, and to which the plurality of light beams passing through the scanning optical system are incident while moving in a main scanning direction includes a light-receiving device having a first light-receiving unit and a second light-receiving unit, which have different intervals from each other in the main scanning direction depending on a position of a sub-scanning direction, all the sizes of the first and the second light-receiving units being sizes covering an overall virtual area in a quadrangular shape surrounding a plurality of light spots in the light-receiving surface.
