Summary:To provide a fixing device that can improve a soaking property and slidability at a fixing nip while making the width of the fixing nip uniform, and an image forming apparatus.SOLUTION: A fixing device comprises: a rotatable endless fixing belt; a heating member that heats the fixing belt; a rotatable pressure member that presses the fixing belt from the outside; a pad member that sandwiches the fixing belt with the pressure member to form a fixing nip; a support member that supports the pad member; a friction reduction sheet that is provided between the fixing belt and pad member and reduces friction with the fixing belt; and a soaking sheet that is provided between the friction reduction sheet and pad member and soaks the fixing belt at the fixing nip.SELECTED DRAWING: Figure 4 【課題】定着ニップの幅を均一にしたまま、定着ニップにおける均熱性及び摺動性を向上させることが可能な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、回転可能な無端状の定着ベルトと、定着ベルトを加熱する加熱部材と、定着ベルトを外側から押圧する回転可能な加圧部材と、加圧部材との間で定着ベルトを挟むことで定着ニップを形成するパッド部材と、パッド部材を支持する支持部材と、定着ベルトとパッド部材との間に設けられ、定着ベルトとの摩擦を低減する摩擦低減シートと、摩擦低減シートとパッド部材との間に設けられ、定着ニップにおける定着ベルトを均熱する均熱シートと、を備える。【選択図】図４
