<P>PROBLEM TO BE SOLVED: To provide a fixing device by which sufficient fixing strength can be obtained in a high-speed area, and an image with a sufficient glossiness can be obtained. Ž<P>SOLUTION: The fixing device includes: a heat roller having a heat source; a first roller which is pressed against the heat roller side to form a first fusion holding part; and a second roller, which is located at the downstream side in the direction of conveying a recording medium of the first roller, and which is pressed against the heat roller side to form a second fusion holding part. The size of a diameter of the first roller is made the size of a diameter of the heat roller or larger, and also the size of the diameter of the heat roller is made larger than the size of the diameter of the second roller.
