FIXING CONTROL DEVICE, FIXING CONTROL METHOD, AND IMAGE FORMING APPARATUS |
| 摘要 |
A fixing control device includes an image detection unit that determines presence of an image in each of areas obtained by division of an image formation region in which the image is formed, a heater selection unit that selects from heaters of a fixing device heaters at positions corresponding to areas in which the presence of the image is determined, a heating amount computation unit that computes a heating amount of a heating area heated by each of the selected heaters in a fixing region corresponding to the image formation region, a change amount computation unit that computes an amount of change of the heating amount between adjoining ones of the heating areas, and a heating amount correction unit that corrects one of the heating amounts of the adjoining heating areas so that the amount of change after the correction is less than a predetermined threshold. |

1. A fixing control device which controls a fixing device including a plurality of heaters to fix an image based on image data to a recording material, the fixing control device comprising:
an image detection unit configured to determine presence or absence of the image in each of a plurality of areas obtained by division of an image formation region in which the image is formed; a heater selection unit configured to select, from the plurality of heaters, heaters at positions corresponding to areas in which the presence of the image is determined; a heating amount computation unit configured to compute a heating amount of a heating area heated by each of the selected heaters in a fixing region corresponding to the image formation region; a change amount computation unit configured to compute an amount of change of the heating amount between adjoining ones of the heating areas; and a heating amount correction unit configured to correct one of the heating amounts of the adjoining heating areas so that the amount of change after the correction is less than a predetermined threshold. |
