FIXING DEVICE, CONTROL METHOD FOR THE SAME, AND IMAGE FORMING APPARATUS |
摘要 |
A fixing device includes: a heat generating rotating member including a heat generating layer; an exciting coil to inductively heat the heat generating layer; a degaussing coil generating an electrical current in response to a magnetic flux generated by the exciting coil and generating a magnetic flux in an opposite direction; an exciting coil controller configured to control energization of the exciting coil by using PWM signals; a degaussing coil controller determining necessity of switching the degaussing coil and to control energization of the degaussing coil. When the degaussing coil controller switches ON/OFF state of the degaussing coil, the exciting coil controller controls ON time periods of the PWM signals so as to be within a range from minimum to maximum values of the ON time periods of the PWM signals corresponding to the ON/OFF state of the degaussing coil stored in a storage unit.
