Fixing device and image forming device

Abstract

The present invention provides a fixing device and an image forming device capable of preventing damage or cracking of the belt while maintaining the rotation of the belt smoothly. The clamping forming part (24) has a base pad (241) determined by the shape of the clamping portion (N), and the base pad (241) includes a base pad (241) that is in contact with the counter rotating body (22) by means of the fixing belt (21). After extending from the contact surface (50) to the upstream side of the recording medium conveying direction, the fixing belt (21) slides and does not contact the extension surface (51) of the counter rotating body (22), and A curved surface (52) that is smoothly and continuously provided from the extending surface (51) to the upstream side in the conveying direction of the recording medium and does not come into contact with the counter rotating body (22).

Description

Technical field [0001] The present invention relates to a fixing device for fixing an image to a recording medium, and an image forming device including the fixing device. Background technique [0002] With regard to image forming apparatuses such as printers, copiers, and facsimile machines, in recent years, market requirements for energy saving and high speed increase have been increasing. [0003] In the image forming apparatus, image forming processes such as electrophotographic method, electrostatic recording, magnetic recording, etc. are adopted, and the recording medium sheet, printing paper, photosensitive paper, electrostatic recording paper, etc. is applied by image transfer method or direct method. In which unfixed toner images are formed. As a fixing device for fixing an unfixed toner image, a fixing device of a contact heating method such as a heat roller method, a film heating method, and an electromagnetic induction heating method is widely used. [0004] As an examp...

Problems solved by technology

[0014] Therefore, if Figure 9 As shown, in the configuration in which the endless belt 100 is guided by the clamping forming member 500, the endless belt 100 will hit heavily into the upstream edge of the clamping forming member 500 when turning, which may cause a loop. Breakage or rupture of ribbon 100

[0015] In addition, in Figure 10 In the shown fixing device, although the sliding sheet 502 is provided on the surface of the base pad 501, when the endless belt 100 rotates, when the sliding sheet 502 hits the edge of the base pad 501 heavily, it will cause wear of the sliding sheet 502

Then, when the function of the sliding sheet 502 drops and the endless belt 100 hits into the edge of the base pad 501 after a while, there will be a problem that the endless belt 100 is broken or broken.
