Problems solved by technology

[0005] However, in the image forming apparatus as described above, when the edge of the fixing belt contacts the anti-snaking sill, the edge of the fixing belt receives a concentrated stress due to strong resistance generated at the edge of the fixing belt.
This concentrated stress can cause damage to the fuser belt

Abstract

A fixing apparatus for an image forming apparatus including a fixing roller, a fixing belt moving endlessly while being in contact with an outer surface of the fixing roller, and an anti-serpentine unit selectively in contact with both lateral outer edges of the fixing belt, which biases the fixing belt toward a center of the fixing roller to prevent serpentine movement of the belt. Therefore, it is possible to address serpentine movement of the fixing belt without causing damage to the fixing belt.

Description

technical field [0001] The present invention relates to an image forming device, and more particularly, to a fixing device for an image forming device using a fixing belt. Background technique [0002] Generally, an image forming apparatus, such as a laser printer, copier, scanner, multifunction printer, facsimile machine, etc., includes a device for melting the developer transferred onto the surface of the recording medium by a known transfer roller and adhering the developer to the recording medium. Fixing device on the surface of the media. Such a fixing device includes a pair of fixing rollers that rotate in close contact with each other, and uses a fixing belt that is supported by at least one fixing roller and a backup roller and moves endlessly. [0003] However, there is a problem in the fixing device of the image forming device using the above-mentioned fixing belt, specifically, the fixing belt moves sideways with respect to its running direction, that is, serpent...
