Abstract
In a belt transfer device according to an embodiment, rotation of a rear side detection roller or a front side detection roller, which contacts with a rib of a transfer belt and is rotated, is converted into linear driving by using a worm gear. The movement of a linear movement shaft is transmitted to a steering roller through a slider. The steering roller is tilted and meandering of the transfer belt is regulated.
Claims13
An image forming apparatus comprising:
- a belt member that travels along a traveling direction;
- an image forming member configured to form an image on the belt member;
- a first detection roller configured to rotate upon contact with a first end of the belt member in a width direction;
- a second detection roller configured to rotate upon contact with a second end of the belt member opposite the first end;
- a tension member configured to move the first detection roller and the second detection roller to an area of contact with the belt member;
- a conversion member configured to convert rotation of the first detection roller or the second detection roller into linear driving;
- a transmission member driven by the linear driving of the conversion member;
- and
- a steering member configured to change the travelling direction of the belt member by an operation of the transmission member.
