PROBLEM TO BE SOLVED: To provide an image forming device improving precision in printing of image constituted by a plurality of lines. SOLUTION: This image forming device includes a first correction means for correcting physical quantity of at least one among charging potential, quantity of light when exposing, and potential of adhered developer so that a first density is obtained, a second correction means for deriving actual line width from the corrected physical quantity and actual density of the detected second developer image and correcting at least one physical quantity further to develop the line being the line width actually, a first preparation means for preparing the first correction information for correcting gradation from the physical quantity corrected by the first correction means and actual density of the detected second and third developer images, a second preparation means for preparing the second correction information for correcting gradation from the physical quantity corrected by the second correction means and the first correction information, and a gradation correction means for correcting gradation of image information by using the second correction information when developing the image constituted by a plurality of lines.
