Abstract
A roller for running a flat belt is formed at its surface by an elastic body. Short fibers are mixed with the elastic body. The short fibers are averagely oriented in a direction radially or peripherally inclined to the roller with a small angle and protrude at their tip portions from the roller surface. Owing to a grip force of the protruding short fibers, the flat belt is running, while decreasing a friction coefficient and obtaining a stability to a variation of temperature and humidity. The short fibers may be oriented in a direction axially, peripherally inclined thereto with a specific angle. When a belt guide member is provided to the roller or flat belt, accurate running of the belt is performed.
