Abstract
A transfer belt having a long service life and an image forming apparatus provided with the belt are provided. A serpentine motion preventing member (6b,) provided on at least one side portion of an inner circumferential surface of an endless belt body (6a, 61a) on which a toner image formed on an image bearing member is transferred on an outer circumference and retained by a retainer groove (R1) formed on a roller serpentine motion preventing member (6b, 61b) away from the belt body (6a, 61a). Accordingly, damage to the belt body (6a, 61a) is prevented.
Claims11
A movable belt stretched around a roller, said belt comprising:
- a serpentine motion preventing member provided on at least one end portion of said belt in a direction perpendicular to a movement direction of said belt in an inner circumferential surface of said belt and engaged with said roller,
- wherein said serpentine motion preventing member is formed in its entirety of a foamed material.
An image forming apparatus comprising:
- an image bearing member;
- and
- a movable intermediate transfer belt stretched around a roller, wherein a toner image on said image bearing member is transferred onto said intermediate transfer belt, and a toner image on said intermediate transfer belt is transferred to a transfer material,
- wherein said intermediate transfer belt comprises a serpentine motion preventing member provided on at least one end portion of said intermediate transfer belt in a direction perpendicular to a movement direction of said intermediate transfer belt in an inner circumferential surface of said intermediate transfer belt and engaged with said roller, and
- wherein said serpentine motion preventing member is formed in its entirety of a foamed material.
An image forming apparatus comprising:
- an image bearing member;
- and
- a movable transfer material delivery belt for bearing a transfer material, said transfer material delivery belt being stretched around a roller, wherein a toner image on said image bearing member is transferred onto a transfer material borne on said transfer material delivery belt,
- wherein said transfer material delivery belt comprises a serpentine motion preventing member provided on at least one end portion of said transfer material delivery belt in a direction perpendicular to a movement direction of said transfer material delivery belt in an inner circumferential surface of said transfer material delivery belt and engaged with said roller, and
- wherein said serpentine motion preventing member is formed in its entirety of a foamed material.
