The inner walls of the fixing member 1 in this embodiment are irregular profiles, and may be all configured as circular arc profiles, and only the local orientation is adjusted, so as to form an alternating structure having the concave portions 11 and the convex portions 12.
The recesses 11 formed therein are recessed toward the rotating shaft 2, which may be understood as a partial hollowing process of the inner wall of the fixing member 1, and the protrusions 12 are protruded toward the rotating shaft 2, which may be understood as a partial raising process of the inner wall of the fixing member 1, so that they are alternately arranged such that the inner wall of the fixing member 1 has an uneven structure.
