Abstract
An image forming apparatus corrects, for uneven density caused by uneven rotation of a rotation speed of a rotation member, and diffuses so as to reduce the uneven density, for a pixel of interest whose density exceeds the upper limit of the output density out of the pixels of the corrected image data, the excess of the density more than the upper limit to a plurality of peripheral pixels while maintaining the center of gravity of the density.
