Patent ID: 8705137

Claim:
An image forming apparatus, comprising: an image forming unit that forms a pattern image on a recording medium, the pattern image having a plurality of different density areas; a detection unit that irradiates light to the plurality of different density areas of the pattern image and detects reflected light from the plurality of different density areas; a determining unit that determines, based on a detection result of the detection unit, an image formation condition for correcting density characteristics of a formed image; a first converting unit that converts, using first conversion setting information, detection results of the detection unit for each of a plurality of different density areas on a first recording medium; a second converting unit that converts, using second conversion setting information, detection results of the detection unit for each of a plurality of different density areas on a second recording medium, which is different from the first recording medium; and a creating unit that creates the second conversion setting information such that an image formation condition for the second recording medium, determined based on a conversion result by the second converting unit, is substantially equal to an image formation condition for the first recording medium, determined based on a conversion result by the first converting unit.
