摘要： Disclosed is a thermal fixing device using at least two heaters for respectively heating center and end portions of a fixing member, in which after the driving of the two heaters is stopped, thermal fixing can be re-started quickly at proper temperatures for both the center and end portions. First, in S100, a judgment is made as to whether the center portion temperature of the thermal roller exceeds 100° C. or not. When it exceeds 100° C., the procedure advances to S110, where the center heater is turned ON two seconds after turning ON the side heater. By thus turning ON the center heater two seconds after the turning ON of the side heater, it is possible to reduce the temperature difference between the two heaters to approximately 8 to 13° C. at the time point when the center heater is turned ON. In this way, the end portions of the thermal roller are heated prior to the center portion thereof, so that, as compared with the case in which the center heater and the side heater are turned ON simultaneously, the temperature difference between these portions is smaller.
摘要翻译：公开了一种热固定装置，其使用至少两个加热器来分别加热固定部件的中心部分和端部部分，其中在两个加热器的驱动停止之后，可以在适当温度下快速重新启动热定影，和端部。首先，在S100中，判断热辊的中心部温度是否超过100℃。当超过100℃时，过程进入S110，其中中央加热器在接通侧加热器两秒钟后打开。通过这样在侧面加热器接通二秒钟之后接通中心加热器，在中央加热器接通的时间点，可以将两个加热器之间的温差降低到大约8至13℃。以这种方式，热辊的端部在其中心部分之前被加热，使得与中心加热器和侧加热器同时接通的情况相比，这些部分之间的温差较小。

摘要： A temperature sensor for detecting the temperature of a heating roller contacts the heating roller with the bottom surface of a contact section provided on the front end of the temperature sensor. A temperature detecting element is disposed on the upper surface of the front end at a position corresponding to the contact section. The front edge of the sensor is bent away from the heating roller. During a printing process, a portion of the toner that is liquefied in the heat fixing process remains on the heating roller and is subsequently deposited on the bottom surface of the contact plate as the heating roller rotates. However, by forming the surface from the contact section to the front edge as a smooth curved surface to eliminate edges or corners that can lead to the accumulation of toner, a clump of toner does not form on the bottom surface of the contact plate.

摘要： An image forming apparatus, such as a laser printer, may use high levels of heat to form images, and some elements may expand and contract with changing temperatures. An apparatus may include a heat roller disposed against a pressure roller, with an endless belt member enclosing the pressure roller. The belt member may also have different frictional characteristics on an inside and outside of the roller, such that when peripheral speeds change due to expansion of the pressure roller, the belt member may be configured to slip against the pressure roller, and maintain a frictional relationship with the heat roller (or a printing medium, such as paper, that is pinched between the rollers). Additionally, the rotational speed of an axis of the pressure roller may be adjusted to compensate for the thermal expansion.
