SUBSTRATE OF SHEET-LIKE MEMBER, FIXING BELT, PLANAR HEATING ELEMENT, METHOD OF MANUFACTURING SUBSTRATE OF SHEET-LIKE MEMBER, FIXING DEVICE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a fixing belt that includes a substrate layer formed of a sheet-like member and having high thermal conductivity and high bending durability, and a fixing device using the fixing belt, and an image forming apparatus.SOLUTION: A fixing belt 71 comprises: an endless belt-shaped substrate layer 201; and at least an elastic layer 202 and a mold release layer 203. The substrate layer 201 is formed of a sheet-like member including a graphite having an integral intensity ratio of a peak(100) to a peak(002)(I(100)/I(002)) of 10 or more in transmission type X-ray diffraction measurement.SELECTED DRAWING: Figure 3
