Abstract
In an image forming apparatus of the present invention, an allowable temperature range of a fixing unit is divided into a plurality of fixing temperature ranges, and image data conversion γ tables respectively suitable for the divided fixing temperature ranges are prepared. A fixing temperature of the fixing unit is measured during image forming. A γ table suitable for the measured fixing temperature can be selected and used. Consequently, even when a reduction in fixing temperature within the allowable temperature range is caused in the fixing unit in the case of continuously outputting color images at a high speed, the resulting change in tint of output images can be reduced.
Claims6
An image forming apparatus comprising:
- conversion unit adapted to perform data conversion of image data;
- image forming unit adapted to form an image based on the converted image data;
- fixing unit adapted to fix the image formed by said image forming unit;
- and
- detection unit adapted to detect a temperature of said fixing unit,
- wherein said conversion unit changes data conversion tables used at the data conversion in correspondence with the detected temperature.
