Zusammenfassung:	A fixing apparatus includes an endless belt, and a pressing member including a base body and an elastic layer formed on the base body. A plurality of pore portions connected to each other are provided in the elastic layer. In a case where a binary image is generated from a three-dimensional image of the elastic layer, a threshold value X μm corresponding to opening processing with which a number of pores derived from the pore portions takes a maximum value is obtained, and then pores derived from the pore portions in the elastic layer are extracted by performing opening processing with a threshold value of 2X μm, an average value of angles θ is 120° or larger and smaller than 150°.
