Abstract
An image forming apparatus includes a conveyance device to convey a recording medium in a first direction and a second direction opposite the first direction; an image forming device; an imaging device; and circuitry to control the image forming apparatus. Controlled by the circuitry, the image forming device forms the colorimetric pattern on the recording medium that has been conveyed in the first direction by a predetermined distance after the marker pattern is formed. Controlled by the circuitry, after the colorimetric pattern is fixed, the circuitry causes the conveyance device to convey the recording medium in the second direction by an amount equivalent to a distance from the marker pattern to an imaging position by the imaging device plus a margin, conveys the recording medium in the first direction until the imaging device detects the marker pattern, and conveys the recording medium in the first direction to a colorimetry position.
