Summary:To reduce, in an area between a first pressure pad and a second pressure pad, a ratio of a portion of an endless belt not pressed by the pressure pads.SOLUTION: A fixing device 8 comprises a heating roller 81, an endless belt 130, a first pressure pad P1, and a second pressure pad P2. The second pressure pad P2 is located on the downstream side in a conveyance direction of the first pressure pad P1. The first pressure pad P1 has a base part P11, and an extension part P12 extending from the base part toward the downstream side in the conveyance direction. In a state in which the first pressure pad P1 is not deformed, a dimension S2 in the direction of movement of the extension part P12 is smaller than a dimension S1 in the direction of movement of the base part P11.SELECTED DRAWING: Figure 3 【課題】第１加圧パッドと第２加圧パッドの間の領域で、エンドレスベルトが加圧パッドに押圧されていない部分の割合を小さくする。【解決手段】定着装置８は、加熱ローラ８１と、エンドレスベルト１３０と、第１加圧パッドＰ１と、第２加圧パッドＰ２とを備える。第２加圧パッドＰ２は、第１加圧パッドＰ１の搬送方向の下流側に位置する。第１加圧パッドＰ１は、ベース部Ｐ１１と、ベース部から搬送方向の下流側に向けて延出する延出部Ｐ１２と、を有する。第１加圧パッドＰ１が変形していない状態において、延出部Ｐ１２の移動方向における寸法Ｓ２は、ベース部Ｐ１１の移動方向における寸法Ｓ１より小さい。【選択図】図３
