IMAGE FORMING APPARATUS AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image forming apparatus and a program for reducing an effect of incorrect measurement of density of a reference image on density correction of a subsequently formed image.SOLUTION: In forming a reference toner image on an intermediate transfer belt 20, a peripheral length of the intermediate transfer belt 20 is estimated (step 102), and the reference toner image is controlled to be formed in an image formation area of the intermediate transfer belt 20 at a density adjusted according to a density adjustment value allocated to the estimated peripheral length in advance (step 114).
