Banding can be prevented and image-quality degradation can be reduced. An image processing apparatus includes first creation means configured to distribute density of image data to a pixel on another scanning line on the basis of a difference between an actual print position of the image data and a reference position and to create position-corrected image data, second creation means configured to correct the image data using a correction value corresponding to a position of the image data and to create density-corrected image data, and generation means configured to generate output image data using the position-corrected image data created by the first creation means and the density-corrected image data created by the second creation means.
