摘要： PROBLEM TO BE SOLVED: To suppress temperature lowering of a fixing roller with an easy constitution and simple control. SOLUTION: In shown by a solid line in the figure, a fixation control target temperature in the standby state after the start-up is set as 150°C, when a printing command is given, the target temperature is changed to 170°C. Thus, a fixation heater is continuously turned on for a prescribed time (about two seconds in this embodiment) just before the sheet enters a fixation nip. Accordingly, the sheet enters the fixation nip in the state where the temperature of the fixing roller tends to increase, then, good fixation can be obtained even just after the start-up. Further, the standby temperature can be maintained with less power, and thus, energy-saving can be achieved. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：以简单的结构和简单的控制来抑制定影辊的温度降低。
解决方案：如图中实线所示，启动后的待机状态下的固定控制目标温度设定为150℃，当给出打印命令时，目标温度变为170 C。因此，在片材进入定影夹持部之前，定影加热器连续地接通规定时间（在本实施例中为约2秒）。因此，在定影辊的温度趋于增加的状态下，片材进入定影夹持部，即使刚刚起动后也能够获得良好的固定。此外，能够以较少的功率保持待机温度，从而可以实现节能。版权所有（C）2009，JPO＆INPIT
