To prevent a trouble that occurs when the temperature of fixing means does not suit a recording sheet.SOLUTION: An image forming apparatus has fixing means that heats a recording sheet on which an image is formed to fix the image to the recording sheet, and fixing temperature control means 110, 120 that control the temperature of the fixing means, and the image forming apparatus has cooling means that cools the recording sheet after the fixing performed by the fixing means, fixing temperature detection means 25h, 25i, 25j that detect the temperature of the fixing means when the recording sheet passes through the fixing means, and cooling temperature detection mans 26h that detects the temperature of the cooling means when the recording sheet passes through the cooling means. The fixing temperature control means control the temperature of the fixing means based on results of detection performed by the fixing temperature detection means and the cooling temperature detection means.SELECTED DRAWING: Figure 6 【課題】定着手段の温度が記録シートに適合しないことで発生する不具合を抑制する。【解決手段】画像が形成された記録シートに該画像を加熱定着させる定着手段と、前記定着手段の温度を制御する定着温度制御手段１１０，１２０とを有する画像形成装置であって、前記定着手段による定着後の記録シートを冷却する冷却手段と、前記記録シートが前記定着手段を通過するときの該定着手段の温度を検知する定着温度検知手段２５ｈ，２５ｉ，２５ｊと、前記記録シートが前記冷却手段を通過するときの該冷却手段の温度を検知する冷却温度検知手段２６ｈとを有し、前記定着温度制御手段は、前記定着温度検知手段及び前記冷却温度検知手段の検知結果に基づいて、前記定着手段の温度を制御する。【選択図】図６
