摘要： A heat generating roller, fixing equipment and an image forming apparatus in which warm-up time is shortened while preventing excessive temperature rise and good fixing performance is realized by preventing occurrence of offset. In the heat generating roller, fixing equipment and image forming apparatus, the heat generating roller is formed principally by laying a high permeability conductive layer and a nonmagnetic conductive layer in layer. When a voltage is applied from a power supply (not shown) to an exciting coil and an AC current flow through it, magnetic flux is generated around the exciting coil and a magnetic field is formed. Since the heat generating roller has the high permeability conductive layer and the nonmagnetic conductive layer laid in layer, magnetic coupling of a system consisting of the heat generating roller and the exciting coil is good at the time of low temperature and heat generation of the heat generating roller is accelerated. When the Curie point is exceeded, skin depth becomes deep and skin resistance decreases, which suppresses generation of Joule's heat and reduces heat generation of the heat generating roller.
摘要翻译：通过防止发生偏移来实现热发生辊，定影装置和图像形成装置，其中预热时间缩短，同时防止过高的温度升高和良好的定影性能。在发热辊，定影设备和图像形成装置中，主要通过在层中铺设高导磁性导电层和非磁性导电层来形成发热辊。当从电源（未示出）施加电压到励磁线圈并且AC电流流过其中时，在励磁线圈周围产生磁通并形成磁场。由于发热辊具有高磁导率导电层和非磁性导电层，所以由发热辊和励磁线圈构成的系统的磁耦合在低温时发热良好，发热量高滚筒加速。当超过居里点时，皮肤深度变深并且皮肤电阻降低，这抑制了焦耳热的产生并且减少了发热辊的发热。

摘要： An electromagnetic induced heating roller (21) comprises a core member (24), an elastic layer (23), induction heating layer (22), and a mold release layer in this order from inside to outside. Further, a magnetic shield layer for preventing a magnetic flux from penetrating into the core member (24) is interposed between the induction heating layer (22) and the core member (24). Out of an alternating magnetic field from a magnetic field generating means, a leakage flux having penetrated through the induction heating layer (22) is trapped by the magnetic shield layer. As a result, most of the impressed alternating magnetic flux is consumed for heating the heating layer (22), resulting in an improvement in the heating efficiency. A trouble is prevented which is generated by heating the bearing of the core member (24).
