PROBLEM TO BE SOLVED: To provide an endless belt which controls leveling during traveling, provide an endless belt travelling device, and also provide an endless photosensitive body capable of forming an image having a high quality. SOLUTION: In the endless belt where a band shaped-elastic body is fixed to the inner surfaces of both side edges by an adhesive layer, I(S) is discretely Fourier transformed according to equation (1) from the power spectrum derived from the result of a discrete Fourier transformation by subjecting the data group of a height x(t) [μm] of the sectional curve obtained by sampling N pieces of the sectional curve at the substrate side boundary of the endless belt of the elastic body at intervals ofΔt [μm] in a horizontal direction is 0.5-13.0. I(S) surely reflects the surface hardness of the elastic body, which influences an image formation, and is an effective parameter which can be controlled. |
