An image fixing control system and method are provided comprising a power supply (100), a power switching unit (110), a heating roller (120), in which a temperature detector (140) detects a temperature of the heating roller (120), and a controller (150) detects a temperature variation slope of the heating roller (120) using the temperature detected by the temperature detector (140) and controls an on and off switching operation of the power switching unit (110) according to the detected temperature variation slope. Accordingly, by varying a duty ratio of power through a phase control using a temperature variation slope of a heating roller (120), a fine control of a fixing system can be performed. In addition, since a temperature variation, that is, overshoot or undershoot, of the heating roller (120) is reduced, a fixing efficiency can be increased. |
