Patent ID: 8830524

Claim:
An image forming apparatus which scans and irradiates a photosensitive member which is rotated in a sub scanning direction, by moving a laser beam according to image data in a main scanning direction, develops a latent image formed on the photosensitive member with the laser beam, and transfers the developed latent image to a recording medium, the image forming apparatus comprising: an acquiring unit configured to acquire output image data created by combining first image data and second image data, the first image data being obtained by correcting image data by distributing, based on a shifting of a print position, each pixel value of the image data to pixels of a plurality of scanning lines, and the second image data being obtained by correcting the image data using a correction value according to a position in the sub scanning direction of the image data; and a driving unit configured to drive the laser beam in accordance with the output image data.
