  • Patent number: 8582180
    Abstract: An image forming apparatus having an image forming unit forming a gradation image includes density detection, gradation correction, and mechanism control units. The density detection unit detects gradation image density. The gradation correction control unit controls a change of gradation characteristic. The mechanism control unit controls the image forming unit and a change of image density, and includes density difference calculation and comparison judging units. The density difference calculation unit calculates density difference between target image density and the image density. The comparison judging unit compares the density difference with reference value and judges the image density to change and the gradation correction unit to operate where the density difference exceeds the reference value, or judges the gradation correction unit to operate where the density difference is below the reference value.
