发热单元、定影单元以及图像形成装置
摘要：
本发明公开了一种发热单元、定影单元以及图像形成装置，所述发热单元包括基板、发热元件以及热破坏元件。发热元件设置在所述基板上，并且通过接收电力而产生热量。热破坏元件设置在所述基板上，并且与所述发热元件串联连接，所述热破坏元件具有正温度系数，并且当被所述发热元件的所述热量加热到高于一特定温度的温度时由于自身发热而导致热破坏。
摘要（英）：

The present invention discloses a heat generating unit, a fixing unit and an image forming apparatus. The heat generating unit includes a substrate; a heat-generating element that is provided on the substrate and generates heat by receiving electric power; and a thermal destruction element provided on the substrate and connected in series to the heat-generating element, the thermal destruction element having a positive temperature coefficient and causing thermal destruction due to self-heating when heated to a temperature higher than a certain temperature by the heat of the heat-generating element.
