Abstract:
1. An image forming apparatus including a processor, the apparatus comprising: a chart data forming unit that forms density correcting chart data to be printed, in which reference density patterns and adjusting density patterns are arranged so that a connection angle at which the reference density patters and the adjusting density patterns are contacted with each other contains all angles, and the adjusting density patterns have different densities in the respective adjusting density patterns; a printing unit that prints a density correcting chart in which the reference density patterns and the adjusting density patterns are arranged adjacent to each other in respective patterns, on the basis of the density correcting chart data; a receiving unit that receives an input of a density adjusting value of a desired pattern, on the basis of comparison of density between the reference density patterns and the adjusting density patterns which has been obtained from visual observation of a user on the printed density correcting chart; and a tone correcting unit that conducts tone correction of the desired pattern, on the basis of the density adjusting value of the desired pattern which has been received by the receiving unit.
