Abstract:
A transport roller includes: a roller body of which a pair of end surfaces face each other by a press work so as to be in a cylindrical shape; and a high friction layer which contains inorganic particles and is provided on a surface of the roller body. Here, the roller body is provided with a joining portion which is formed by separating the pair of end surfaces. In addition, an average particle diameter of the inorganic particle is larger than a distance between the pair of the end surfaces of the roller body on an outer peripheral surface side thereof.
