Abstract:
1. An image forming apparatus comprising: a chart data generating unit that generates density adjustment chart data used to juxtapose and print reference patterns and adjustment patterns; a printing unit that prints a density adjustment chart where the reference patterns and the adjustment patterns of each pattern are juxtaposed, based on the density adjustment chart data; a receiving unit that receives the input of a density adjustment value of an arbitrary pattern based on a comparison of the contrasting density between the reference patterns and the adjustment patterns of the printed density adjustment chart performed by the visual recognition of the user; a gradation correcting unit that corrects gradation of the arbitrary pattern based on the density adjustment value of the arbitrary pattern that is received by the receiving unit; and a reconstructing unit that reconstructs density adjustment chart data used to juxtapose and print the reference patterns and density-corrected adjustment patterns for only pattern data of the patterns where the receiving unit receives the density adjustment value, wherein the densities of all patterns are corrected by performing:
