Abstract:
1. An optical scanning device for scanning a surface to be scanned with a plurality of light beams, comprising: at least one light source in which a plurality of light-emitting units are two-dimensionally arranged; a deflector for deflecting a plurality of light beams from the at least one light source; an optical system for condensing the plurality of light beams deflected by the deflector on the surface to be scanned; and an adjustment device for adjusting a total light volume of light emission from the plurality of light-emitting units; and a control device to control the optical scanning device, wherein the control device is configured to read out a resist of the scanned surface in a sub-scanning direction, identify a light-emitting unit at a start of writing from the light-emitting based on the resist in the sub-scanning direction, select a plurality of light-emitting units forming one pixel based on the light-emitting unit at the start of writing, and read out a deformation amount of pixel in the scanned surface by the selected light-emitting units, and wherein the control device is configured to control the adjustment device so that the adjustment device adjusts a total light volume of light emission of the selected light-emitting units based on the deformation amount of the pixel.
