Image formation apparatus having unit for correcting irregularities in density of image data after binarization

摘要

An image formation apparatus is equipped with a recording head having a plurality of recording elements for forming an image on a recording medium. A binarized image data storage unit stores binarized image data for on-off control of the recording elements of the recording head. A correction data storage unit stores density irregularity correction data for correcting irregularities in density which occur when the recording elements of the recording head are respectively driven to form the image for each of the recording elements. A density irregularity correction unit corrects, prior to the image formation, the binarized image data stored in the binarized image data storage unit on the basis of the density irregularity correction data stored in the correction data storage unit.
