To provide an intermediate transfer body excellent in the separability of recording media and preventing a failure such as an image defect.

The surface of a valcanized core bar 31 is roughened, and a base material rubber 32 is molded on the rough surface of the core bar 31. The surface of the rubber 32 is ground to be a ground surface 32a, and the rubber 32 is released from the core bar 31 so as to form a coating layer 33 on a surface (base material rough surface) 32b opposed to the surface 32a and obtain an intermediate transfer member (high resistance belt) 34. Then, the member 34 is attached to a supporting member (for example, a supporting member obtained by forming a conductive elastic layer on a conductive cylinder) by the use of the ground surface, so that the intermediate transfer body is obtained. For example, the surface of the core bar 31 is made the rough surface whose ten-point average roughness is 15 to 30 μm and whose pitch average value is 50 to 150 μm, and the thickness of the layer 33 is made smaller than the ten-point average roughness of the rubber 32.
