Image forming apparatus, calibration method, and drying determination method |
摘要 |
An image forming apparatus includes a printing unit that prints at least one object image using a color material; a color information acquiring unit that acquires color information of the object image; and a control unit that starts one of colorimetry of the object image using the color information acquired by the color information acquiring unit and color adjustment of the printing unit after a variation amount of color information of the object image measured at different points of time is equal to or smaller than a predetermined threshold. |

1. An image forming apparatus comprising:
a conveyor that conveys a recording medium; a printing unit that prints a plurality of patches using color material in a conveying direction; a color information acquiring unit that acquires color information of a representative patch that is a patch closest to an upstream side in the conveying direction among the plurality of patches; and a control unit that starts one of colorimetry using color information of the plurality of patches and color adjustment of the printing unit after a variation amount of color information of the representative patch measured at different points of time is equal to or smaller than a predetermined threshold. |
