发明名称 CORRECTION METHOD FOR IMAGE FORMING APPARATUS
摘要 A correction method for an image forming apparatus including a light source including a plurality of light emitting points, a photosensitive member configured to rotate in a first direction so that a latent image is formed thereon with light beams emitted from the light source, and a deflecting unit configured to deflect the light beams emitted from the light source in a second direction orthogonal to the first direction to form scanning lines, the correction method including a correction step of correcting sparseness and denseness of density in the first direction caused by deviation of the scanning lines in the first direction by moving a predetermined pixel in the first direction in accordance with the deviation of the scanning lines and causing a pixel value of the predetermined pixel to be output in accordance with a movement of the predetermined pixel.

主权项 1. A correction method for an image forming apparatus, the image forming apparatus comprising: a light source including a plurality of light emitting points;a photosensitive member configured to rotate in a first direction so that a latent image is formed on the photosensitive member with light beams emitted from the light source; anda deflecting unit configured to deflect the light beams emitted from the light source to move light spots of the light beams radiated to the photosensitive member in a second direction orthogonal to the first direction to form scanning lines, the correction method comprising a correction step of correcting sparseness and denseness of density in the first direction caused by deviation of the scanning lines in the first direction, by moving a predetermined pixel in the first direction in accordance with the deviation of the scanning lines and causing a pixel value of the predetermined pixel to be output in accordance with a movement of the predetermined pixel.
