Abstract

An image forming apparatus includes an image bearing member bearing an image; a transfer member having the image transferred thereto from the image bearing member; a correction-image-formation control unit that causes, on the transfer member, a bias correction image to be formed based on an uncorrected bias and a first parameter-correction image to be formed immediately behind the bias correction image based on the uncorrected bias and an uncorrected image-formation parameter; a bias correcting unit obtaining a corrected bias by correcting the uncorrected bias based on the bias correction image; a bias determining unit for determining whether the corrected bias is within a predetermined range defined based on the uncorrected bias; and a parameter correcting unit obtaining, if the corrected bias is within the predetermined range, a corrected image-formation parameter by correcting the uncorrected image-formation parameter based on the first parameter-correction image.
