Abstract
A solid scanning optical writing device has multiple optical elements which are aligned in a zigzag fashion to form two lines in a main scanning direction. Each of the optical elements is turned ON/OFF in accordance with image data to write an image. In the solid scanning optical writing device, the amount of light output from each of optical elements is corrected based on correction data. The correction data is obtained by detecting light amount distribution of each of the two lines and obtaining ridge light amount and trough light amount from the detected light amount distributions.
