    • PROBLEM TO BE SOLVED: To provide an image forming method that forms a durable and high-quality beautiful image by forming an overcoat later on an oil-less fixing toner image.SOLUTION: A toner image is formed with toner containing wax. The toner image is fixed on a recording medium by use of an oil-less fixing machine, to form an image with an overcoat layer. In an FT-IR spectrum obtained by measuring by ATR a portion of the toner image with maximum toner adhered thereon under a predetermined condition, the ratio Ab/Aa between peak area Aa of 2896-2943 cmand peak area Ab of 2946-2979 cmis 3.0-7.0, or the ratio Ab'/Aa' between peak area Aa' of 791-860 cmand peak area Ab' of 2834-2862 cmis 0.004-0.014.
    • 要解决的问题:提供一种通过在无油定影调色剂图像上形成外涂层形成耐用且高质量的美丽图像的图像形成方法。解决方案:用含蜡的调色剂形成调色剂图像。 通过使用无油定影机将调色剂图像固定在记录介质上,以形成具有外涂层的图像。 在通过ATR测量得到的一部分调色剂图像的最大调色剂在预定条件下粘附在其上的FT-IR光谱中,2896-2943cm的峰面积Aa与2946-2979cm的峰面积Ab之间的比Ab / Aa为3.0 -7.0,或者峰值区域Aa'在791-860cm之间的比率Ab'/ Aa'和峰面积Ab'为2834-2862cm之间的比率为0.004-0.014。
