Abstract
The bottoms 225 of circumferential groove 22 are equidistant from the axis of rotation 215 and constitute the sides of the column, the axes of rotation of which are common. The sides 226 and 227 of the circumferential groove 22 are not normal to the axis of rotation 215, and are beveled to form an acute angle to the bottom 225. That is, the sides 226 and 227 of the circumferential groove 22 form sides of cones the axes of rotation of which are common. The width of the circumferential groove 22 becomes widened from the surface to the inside. Resin 26 is coated on the surface of the circumferential groove 22 in such a manner that the coated surface has a substantially constant width. In this embodiment, a nylon type resin is coated with little peeling-off during use of the roller.
