ABSTRACT:
An image forming system includes a generator for generating an image signal representing a predetermined test image having a plurality of tone levels, an image forming device for forming the predetermined test image on a recording medium based on the signal, a first measuring device for measuring density levels of the formed predetermined test image, corresponding to each of the plurality of tone levels of the image signal, a controller for determining characteristics of a change of density levels in the predetermined test image to a change of tone levels in the image signal based on a plurality of density levels measured by the first measuring device, and for making a conversion data table for converting tone levels of an input image signal in accordance with the characteristics, a designator for generating instructions for designation a correction of the conversion data table, a transferring device for transferring the image formed on the recording medium to a recording sheet, a second measuring device for measuring density levels of the image on the recording sheet, wherein the controller controls the generator, the image forming device, and the transferring devices to correct the conversion data table based on the density levels measured by the second measuring device.
