PROBLEM TO BE SOLVED: To provide an electrophotographic member capable of maintaining the transfer characteristics even when images are repeatedly transferred, and obtaining a good image over a long period of time. In an electrophotographic member having a multilayer structure or a single layer structure, the outermost layer of the electrophotographic member satisfies the following conditions A to C: A: The outermost layer is: The ratio of the number of fluorine atoms to the number of carbon atoms in the outermost layer is 0.10 or more and 0.40 or less, and B: 19F-NMR spectrum of the outermost layer, containing perfluoropolyether and a binder resin , The relaxation time T2 at 22 ° C. of the peak derived from the CF2 portion of PFPE is 13 ms or more. C: The total content of the CF3 portion, the CF2 portion and the CF portion in the binder resin is 5% by mass or less. . [Selection] Figure 1 |
