To provide a roller capable of maintaining the advancing direction of a belt-like body or the like constant, in the roller into which the belt-like body such as a belt and a sheet-like body such as copy paper obliquely enter, or into which the belt-like body and the sheet-like body may enter.
In the rollers (18 and 20) which guide the belt-like body or the like, and into which the belt-like body or the like obliquely enters with respect to the axis, or into which the belt-like body or the like may enter, the rollers are characterized by comprising a friction reducing means (32) capable of moving the belt-like body or the like in a direction parallel with the rotational axis of the rollers by reducing friction generated between the rollers and the belt-like body or the like. In such a constitution, even if the belt-like body tries to move the roller in the direction of the rotational axis, since a slip is caused by a friction reducing means, the movement in its direction is blocked, and the advancing direction is maintained constant.
