PROBLEM TO BE SOLVED: To stably secure an excellent image state without dispersion by restraining the dispersion of the image state in a recording body carrying direction. SOLUTION: When fixing test images TA to TC are formed on the recording body (S1), a supervisory control part reads test image data (S3) and calculates toner requirement adhesion amount from the test image data obtained at S3 (S4). When an image information detection part detects the intensity 1b (IbA to IbC) of the regularly reflected light of the images TA to TC and the emitted light intensity 1a (IaA to IaC) of a halogen lamp, the measured glossiness of the images TA to TC is calculated by using the detected intensity (S5). Furthermore, the real adhesive amount of toner adhering to the images TA to TC is estimated based on the surface temperature (fixing temperature) of a heating roller and each measured glossiness calculated at S5 (S6). Then, a charge voltage value is corrected so that the proper amount of toner may adhere to the recording body S without dispersion (S7 to S12). |
