摘要：
An image forming apparatus is arranged such that one reference test pattern image expressed in a tone expression is formed on the predetermined image bearing member, the tone expression being different from a tone expression of an image formed in the print modes that carry out a normal print process, and density of the formed reference test pattern image is detected, and subsequently sets of density correction data for the print modes are created based upon the detected density.
