摘要： An image forming apparatus includes: an image former that forms an image, which is desired by a user and different from a predetermined pattern, on a sheet; an output information detector that detects output information on a first image formed on a first sheet by the image former; and a hardware processor that: acquires an correction amount of a third image, which is formed on a third sheet after the first sheet and a second sheet, according to a detection result of the first image by the output information detector and image information on a second image formed on the second sheet after the first sheet by the image former; and controls the image former so as to correct the third image based on the correction amount acquired by the hardware processor.

摘要： An image forming apparatus that forms an output image corresponding to input image data on an image carrier by superimposing toner images of colors, includes a hardware processor that: detects color information of the output image for every pixel region; converts color information of the input image data for every pixel region and color information of the output image for every pixel region into indexes which define colors in predetermined color space coordinates; extracts a pixel region in which the color information of the output image is different from the color information of the input image data, and corrects the color information of the input image data with respect to the extracted pixel region; and stores the color information of the input image data as data for calibration in combination with the color information of the output image and image forming conditions when forming the output image.
