PROBLEM TO BE SOLVED: To provide a tubular body that has excellent stability of electric resistance.SOLUTION: There is provided a tubular body 10 (endless belt 10) including a thermoplastic resin and a conductive agent, where the thermoplastic resin has a resin layer that forms a sea part to be a matrix phase, and with respect to the ratio of an area having a bigger value, of the ratio of an area occupied by the sea part in a range from a front face part of the resin layer up to 10 μm in the thickness direction, and the ratio of an area occupied by the sea part in a range from a rear face part of the resin layer up to 10 μm in the thickness direction, the ratio of an area occupied by the sea part in a range from the center part in the thickness direction of the resin layer as the center to the front face side and the rear face side up to 5 μm, respectively, is larger by 3% or more and 15% or less.SELECTED DRAWING: Figure 1 |
