FUSING UNIT, CONTROL METHOD THEREOF AND IMAGE FORMING APPARATUS EMPLOYING THE SAME

摘要

Disclosed are a fusing unit capable of a variable fusing pressing force, a control method thereof and an image forming apparatus employing the same. The fusing pressing force may be selectively varied so as to apply a lesser force at the initial stage of the operation of the fusing unit, and may be increased to a desired level of force suitable for fusing operation so as to minimize excessive torque in a driving motor that rotationally drives the fusing device.
