In order to reduce the storage capacity of a memory for a density adjusting table and change the density adjustment range with a relatively high degree of freedom, a density characteristic adjusting table section corresponding to set density based on reference data of light, center and dark for density characteristic adjustment previously stored in a correction data table section is created in a table forming section, a density characteristic adjustment value corresponding to an input image signal from a scanner section is derived by effecting the linear interpolation according to neighboring density characteristic adjustment values based on the input image signal in a density characteristic adjustment value calculating section, and the input image signal is corrected by use of the derived density characteristic adjustment value in a density characteristic adjusting section and then output to a printer section as an output image signal.
