Abstract:
1. An image forming apparatus that has a calibration function of forming a predetermined image on a recording medium, reading the predetermined image formed on the recording medium, and setting image forming conditions based on information on the read predetermined image, comprising: a first reading unit configured to read a predetermined image on a first recording medium; a second reading unit provided separately from said first reading unit and configured to read the predetermined image on the first recording medium; a first configuration unit configured to execute the calibration function using the first recording medium and the first reading unit, form a predetermined image on a second recording medium other than the first recording medium, in a state where image forming conditions obtained as a result of the execution of the calibration function are set, cause said first reading unit to read the predetermined image formed on the second recording medium, and configure a first conversion table based on the read predetermined image on the second recording medium; a second configuration unit configured to configure a second conversion table based on the first conversion table configured by said first configuration unit, using a correlation table representing a correlation in reading characteristic between said first reading unit and said second reading unit; and a setting unit configured to be operable when said first reading unit is used to execute the calibration function using the second recording medium, to set the image forming conditions based on image information read by said first reading unit and the first conversion table, and when said second reading unit is used, to set the image forming conditions based on image information read by said second reading unit and the second conversion table.
