Abstract
A belt-deviation suppression structure includes a contact member, receivers, and multiple link members. The contact member is in contact with a rotatable belt and extends longitudinally in an intersecting direction that intersects a moving direction of the belt. The receivers are provided at opposite sides of the contact member in the intersecting direction and receive a pressing force from the belt as the belt moves in the intersecting direction. The link members are arranged in the intersecting direction. Each link member has a first end that is connected to a base in a rotatable manner about an axis extending in the moving direction and has a second end that is connected to the contact member in a rotatable manner about an axis extending in the moving direction.
Claims6
A belt-deviation suppression structure comprising:
- a contact member that is in contact with a rotatable belt and that extends longitudinally in an intersecting direction that intersects a moving direction of the belt;
- receivers that are provided at opposite sides of the contact member in the intersecting direction and that receive a pressing force from the belt as the belt moves in the intersecting direction;
- and
- a plurality of link members that are arranged in the intersecting direction, each link member having a first end that is connected to a base in a rotatable manner about an axis extending in the moving direction and having a second end that is connected to the contact member in a rotatable manner about an axis extending in the moving direction,
- wherein a length of the contact member is set to be equal to or larger than a width of the rotatable belt, and the contact member retains the rotatable belt, the rotatable belt contacting the contact member from end to end, an entirety of the contacting being straight, in the intersecting direction.
A transfer device comprising:
- a rotatable belt;
- a transfer unit that transfers a developer image on the belt onto a recording medium;
- and
- a belt-deviation suppression structure comprising:
- a contact member that is in contact with a rotatable belt and that extends longitudinally in an intersecting direction that intersects a moving direction of the belt;
- receivers that are provided at opposite sides of the contact member in the intersecting direction and that receive a pressing force from the belt as the belt moves in the intersecting direction;
- and
- a plurality of link members that are arranged in the intersecting direction, each link member having a first end that is connected to a base in a rotatable manner about an axis extending in the moving direction and having a second end that is connected to the contact member in a rotatable manner about an axis extending in the moving direction,
- wherein the belt-deviation suppression structure suppresses deviation of the belt in the intersecting direction.
An image forming apparatus comprising:
- an image bearing member that is disposed facing a belt and that bears a developer image;
- a transfer device comprising:
- a rotatable belt,
- a transfer unit that transfers a developer image on the belt onto a recording medium;
- and
- a belt-deviation suppression structure comprising:
- a contact member that is in contact with a rotatable belt and that extends longitudinally in an intersecting direction that intersects a moving direction of the belt;
- receivers that are provided at opposite sides of the contact member in the intersecting direction and that receive a pressing force from the belt as the belt moves in the intersecting direction;
- and
- a plurality of link members that are arranged in the intersecting direction, each link member having a first end that is connected to a base in a rotatable manner about an axis extending in the moving direction and having a second end that is connected to the contact member in a rotatable manner about an axis extending in the moving direction,
- belt in the belt deviation suppression structure suppresses deviation of the belt in the intersecting direction;
- and
- an auxiliary transfer unit that transfers the developer image on the image bearing member onto the belt.
