A toner image fixing apparatus has a fixing roller, a pressing roller, and a heating roller.
一种定影装置具有一个定影辊、一个加压辊和一个加热辊。
Induction heating roller device, heating roller, photographic fixing equipment and imaging device.
感应加热辊装置，加热辊，定影设备和成像设备。
A method and an apparatus to control power supplied to a heating roller and a phase control circuit corresponding to the method or the apparatus.
一种用于控制提供到加热辊的功率的方法和设备及相应于该方法和设备的相位控制电路。
In addition, since a temperature variation, that is, overshoot or undershoot, of the heating roller is reduced, a fixing efficiency can be increased.
此外，由于减少了加热辊的温度变化即过冲或下冲，所以可提高图像的定影效率。
Accordingly, by varying a duty ratio of power through a phase control using a temperature variation slope of a heating roller, a fine control of a fixing system can be performed.
因此，通过使用加热辊的温度变化斜率的相位控制来改变功率的占空比，可执行对定影系统的精细控制。
