<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that prevents damage to a side face of an endless belt, by decreasing pushing force applied to the endless belt in a direction perpendicular to the direction of conveyance of the endless belt. <P>SOLUTION: The image forming apparatus includes a plurality of rotors, and the endless belt that is laid across the plurality of rotors in a tensioned condition and rotated by the rotors. Herein, at least one of the plurality of rotors is provided, at a first end, with a belt restraining member that has a restraining face for restraining displacement of the endless belt toward the first end and that is rotatable with respect to the rotor; and the belt restraining member is arranged such that an angle between the restraining face of the belt restraining member and a rotation shaft of the rotor is greater at a contact start point at which the endless belt begins contact with the belt restraining member than at a contact end point at which the endless belt ends contact with the belt restraining member. <P>COPYRIGHT: (C)2008,JPO&INPIT |
