Zusammenfassung:To provide a fixing device and an image forming apparatus capable of stabilizing a conveyance attitude from the first recording medium heated by a preheating unit in comparison with a case where a detection unit is arranged between the preheating unit and a spraying unit.SOLUTION: A fixing device 100 includes: a preheating unit 102 for heating a sheet member P in a non-contact state; a spraying unit 170 arranged so as to be opposite to the preheating unit 102; a detection unit 200 arranged on an upstream side of the preheating unit 102 in a conveyance direction of the sheet member P; and a main heating unit 120 arranged on a downstream side of the preheating unit 102. The sheet member P to be conveyed is to pass between the spraying unit 170 and the preheating unit 102. The detection unit 200 detects a deflection of the sheet member P to be conveyed to detect a conveyance attitude of the sheet member P. The control unit controls each of a plurality of fans 172 arranged in the spraying unit 170 on the basis of a detection result of the detection unit 200.SELECTED DRAWING: Figure 1 【課題】検出部が予備加熱部と吹付け部との間に配置されている場合と比して、予備加熱部によって加熱される1枚目の記録媒体から搬送姿勢を安定させることができる定着装置、及び画像形成装置を得る。【解決手段】定着装置100は、非接触状態でシート部材Pを加熱する予備加熱部102と、予備加熱部102と対向するように配置される吹付けユニット170と、シート部材Pの搬送方向において、予備加熱部102の上流側に配置される検出部200と、予備加熱部102の下流側に配置される本加熱部120と、を有する。搬送されるシート部材Pは、吹付けユニット170と予備加熱部102との間を通過するようになっている。検出部200は、搬送されるシート部材Pの撓みを検出することで、シート部材Pの搬送姿勢を検出する。制御部は、検出部200の検出結果に基づいて、吹付けユニット170に備えられる複数のファン172を個別に制御する。【選択図】図1
