A fixing device slide member has a surface 40a of a sheet body 40, which surface is made of heat-resistant resin. A specific wear rate on the surface 40a of the sheet body 40 in the ring-on-disc test is 10×10−8 mm3/(N×m) or less on condition that a counterpart material is aluminum, roughness Ra is equal to 0.2 micrometer, PV is equal to 51.2 MPa×m/min, and measuring time is 50 hours. Thus, the surface 40a of the sheet body 40 is enhanced in wear resistance so as to be free from generation of worn powder, which suppresses torque increase in a pressurizing belt caused by the worn powder. |
