Abstract
A determination unit determines density correction characteristics to be applied to correct density characteristics based on a reading result obtained by a reading unit. A measuring unit measures a density value of the image pattern formed on the image carrier by the image forming unit at the first image forming speed by applying the density correction characteristics. A reference density value storage unit stores, as a reference density value, the density value of the image pattern measured by the measuring unit. A creation unit creates modification data to modify the density correction characteristics for a second image forming speed from a difference between a density value of an image pattern formed on the image carrier by the image forming unit at the second image forming speed by applying the density correction characteristics, and the reference density value stored in the reference density value storage unit.
