IMAGE FORMING APPARATUS AND FUSER DRIVING CONTROL METHOD

摘要

An image forming apparatus is provided. The image forming apparatus includes: a heating roller heated using a first heater unit disposed in the center thereof and second heater units disposed on both sides of the first heater unit; a pressure roller in pressing contact with the heating roller to form a nip; a first sensor for detecting the temperature of a central area of the heating roller; a second sensor for detecting the temperature of a side area of the heating roller; and a controller for individually controlling the first heater unit and the second heater units according to the respective temperatures measured by the first sensor and the second sensor when the temperature measured by the second sensor is lower than a predetermined first temperature, and commonly controlling the first heater unit and the second heater units according to the temperature measured by the first sensor when the temperature measured by the second sensor is equal to or higher than the predetermined first temperature.
