Summary:To improve the heat efficiency and energy-saving property of a heating device and to reduce size, weight, and cost.SOLUTION: The heating device includes an endless rotation member (fixing belt 310), a heating source (halogen heater 361) which emits radiation heat, a nip forming member 380 which is heated by the radiation heat, and an opposite member (pressure roller 320) which holds the rotation member 310 between the opposite member and the nip forming member 380, to form a nip part SN through which a sheet being heated passes. A reflection surface 362 which reflects the radiation heat except the radiation heat directly directed to the nip forming member from the heating source toward the nip forming member is disposed on the surface of the heating source.SELECTED DRAWING: Figure 3 【課題】加熱装置の熱効率と省エネ性を向上すると共に軽量小型化とコストダウンを図る。【解決手段】無端状の回転部材（定着ベルト３１０）、輻射熱を発する加熱源（ハロゲンヒータ３６１）、輻射熱で加熱されるニップ形成部材３８０、ニップ形成部材３８０との間で回転部材３１０を挟むことで被加熱シートが通過するニップ部ＳＮを形成する対向部材（加圧ローラ３２０）を備えた加熱装置であって、加熱源からニップ形成部材に直接向かう輻射熱以外の輻射熱を、ニップ形成部材の方向に反射する反射面３６２が加熱源の表面に配設されている。【選択図】図３
