Abstract:
An image forming apparatus includes: an image forming unit including a rotating member and being configured to form an image on a paper sheet in accordance with print job data; a rotation position detecting unit configured to detect a rotation position of the rotating member; an image density detecting unit configured to detect a density in an image formed on an image carrier; an image information analyzing unit configured to analyze image information in the print job data; a density profile managing unit configured to form a correction patch image on the image carrier, and create and manage a density profile indicating periodical density unevenness; a correction data creating unit configured to create correction data; a density correcting unit configured to perform density correction; and a density correction control unit configured to predict an appearance of periodical density unevenness, and set conditions for the density correction.
