Disclosed is an image forming apparatus and a control method thereof in which occurrence or removal of a paper rolling state in a fusing device is judged based on temperature of the fusing device. The apparatus includes a temperature sensor to sense temperature of the fusing device, a memory to store information about occurrence or removal of the paper rolling state, and a controller to judge occurrence or removal of the paper rolling state. The controller detects an initial temperature of the fusing device when the apparatus is turned off and then on in a state in which the information about occurrence of the paper rolling state is stored in the memory, heats the fusing device by applying power thereto for a predetermined time based on the initial temperature, and judges occurrence or removal of the paper rolling state based on temperature of the fusing device detected after power application.
