| Zusammenfassung: | To provide a fixing device that can improve the assemble property of a heat source to a heat source support member, and an image forming apparatus.SOLUTION: A fixing device comprises: an endless first rotating body; a second rotating body that is in pressure contact with the first rotating body; a heat source 23 that heats the first rotating body; a heat source support member 202 that supports the heat source 23; and a soaking member that is in contact with the first rotating body to make uniform the temperature in a rotation axis direction of the first rotating body. The heat source 23 is fitted to and supported by the heat source support member 202 only by loose fitting.SELECTED DRAWING: Figure 4
【課題】熱源の熱源支持部材に対する組み立て性を改善することができる定着装置および画像形成装置を提供する。【解決手段】定着装置は、無端状の第一回転体と、第一回転体に加圧接触する第二回転体と、第一回転体を加熱する熱源２３と、熱源２３を支持する熱源支持部材２０２と、第一回転体に当接して第一回転体の回転軸方向の温度を均一化する均熱部材を備えている。そして、熱源支持部材２０２と熱源２３との間は隙間嵌めによる嵌合のみで支持している。【選択図】図４ |
