Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 電磁誘導加熱方式の加熱装置について、発熱 域であるニップ部の長手方向の発熱分布を任意に調整す ることができるようにし、ニップ部の温度検知素子設置 対応位置や端部の熱量不足を解消してニップ部内の発熱 分布を均一化させ、局部的な加熱不足・定着不良の発生 をなくすこと。 【構成】 磁場発生手段2・3により導電部材に磁場を 作用させて該導電部材に発生する渦電流による該導電部 材の発熱により被加熱材を加熱する電磁誘導加熱方式の 加熱装置であり、前記磁場発生手段の励磁コイル3が巻 かれる複数の芯材2a・2bを少なくとも1方向に配列 したこと、複数の芯材の材質が1種類以上であること、 複数の芯材と導電部材との距離が0.001mmから1 0mmであること、励磁コイルが、芯材を配列保持する ためのホルダーと、このホルダーに嵌合するコイルから 構成されたこと等。 (57) [Abstract] [Purpose] Regarding the electromagnetic induction heating type heating device, it is possible to freely adjust the heat generation distribution in the longitudinal direction of the nip part, which is the heat generation area, and the position corresponding to the temperature detection element installation position of the nip part. To eliminate the lack of heat at the edges and to even out the heat distribution in the nip area to eliminate localized heating shortages and fixing defects. A heating device of an electromagnetic induction heating system for heating a material to be heated by heat generation of the conductive member by an eddy current generated in the conductive member by applying a magnetic field to the conductive member by the magnetic field generating means 2 and 3. A plurality of core materials 2a and 2b around which the exciting coil 3 of the magnetic field generating means is wound are arranged in at least one direction, and the material of the plurality of core materials is one or more. The distance between the plurality of core members and the conductive member is 0.001 mm to 1 It is 0 mm, the exciting coil is composed of a holder for holding the core material in an array, and a coil fitted in the holder.
