Abstract
An optical scanner includes a multi beam light source, a scanning optical system, and a controller. The controller specifies selected beams, and changes light quantities of the respective selected beams at the same change timing based on the same profile data at respective positions in the main scanning direction which are fixedly determined as light quantity change positions. When the position of a center region in an arrangement width of the plurality of selected beams is moved in the main scanning direction in response to a selected mode of the beams, in the profile data, the controller derives a shift light quantity at a position shifted in the main scanning direction by an amount corresponding to the movement of the position of the center region, and the light quantity is modified so that the shift light quantity is used at the light quantity change position.
