Solid scanning optical writing device, and light amount correction method and light amount measuring device therefor |
摘要 |
In a solid scanning optical writing device that writes images on a photoreceptor by turning ON/OFF many light shutter elements aligned in an alternating fashion in two rows in the main scanning direction, single-row illumination and double-row illumination of the light shutter elements are alternately performed on a time sharing basis prior to the image writing in order to perform high-quality light amount correction. The positions of the light shutter elements are identified from the light amount data obtained from single-row illumination, and the transmitted light amount for each light shutter element during double-row illumination is sought from the light amount data obtained from double-row illumination. Calculation for shading correction is then performed from these sets of data.
