Abstract:
Density-correction-table lists showing an amount of density changes in respective density levels of images that exist after an image having a predetermined density has been printed on a predetermined number of sheets are maintained. The amount of density changes in the respective density levels for an image ratio that exists after the predetermined number of sheets have been printed on and for the predetermined number of sheets that have been printed on are obtained with reference to values in the maintained density-correction-table lists. A density correction characteristic is determined using the obtained amount of density changes.
