AI Technical Summary
Technical Problem
Conventional fixing devices with belt regulating members suffer from wear and deformation of the fixing belt ends, leading to potential breakage due to contact with the belt guide, which compromises the belt's cylindrical shape and durability.
Method used
A fixing device design featuring a cylindrical fixing member held by a frame with a groove and through-hole structure, incorporating a biased contact member to guide the belt ends, reducing wear and maintaining the cylindrical shape, thereby enhancing durability.
Benefits of technology
The design effectively limits wear and deformation of the fixing belt ends, improving durability by allowing the belt ends to move in the direction of the pulling force and maintaining a circular shape, thus preventing breakage.

Abstract
To provide a fixing device with improved durability against tearing of the fixing belt. [Solution] The fixing device 10 comprises a cylindrical fixing belt 12 in the axial direction, a belt guide 20 that holds both ends of the fixing belt 12, a frame 27 that supports the belt guide 20, and a pressing member 19 that pressurizes the fixing belt 12 while contacting the fixing belt 12 in a direction intersecting the axial direction. The belt guide 20 has a flange portion 21 that contacts and is fixed to the frame 27, and an upright portion 22 provided adjacent to the flange portion 21 that contacts the inner circumference of the fixing belt 12, and a groove portion 23 provided on the flange portion 21 on the outer circumference of the upright portion 22 that can receive the end of the fixing belt 12, and a through hole 24 that connects the surface of the flange portion 21 facing the frame 27 and the groove portion 23, and a contact member 26 that is disposed inside the through hole 24 and biased to contact the end of the fixing belt 12.
