[0006] Furthermore, what is experienced when the downtime of the joint of the rib members 196 and 198 in either side edge while keeping the state of being wound on the same roll extended to a long period of time is that the intermediate transfer belt 194 is likely to be subjected to other effects. and this causes bending strain, acute-angle bending, etc. to occur at the joint portion, and thus causes deterioration in the durability of the intermediate transfer belt 194

Embodiment Construction
[0027] figure 2 is a diagram showing an overview of the image forming apparatus 50 according to the embodiment of the present invention. The image forming apparatus 50 is an image forming apparatus that forms a multi-color or monochrome image on predetermined paper (recording medium) based on image data transmitted from the outside, and includes an image forming section 82 and a document reading section 58 .
[0028] The image forming section 82 includes four image forming stations that respectively form black (K), cyan (C), magenta (M), and yellow (Y) color images. Each of the image forming stations includes a developing device 91 , a photosensitive drum 90 , a cleaning unit 93 and an electrostatic charger 92 .
[0029] The image forming section 82 further includes an optical scanner 88, an intermediate transfer belt unit 95, a fixing unit 74, a paper feed cassette 71, a first output tray 80, a second output tray 100, a plurality of baffles (not shown), etc.

An intermediate transfer belt includes a belt body and a first and a second travelling guide ribs. The first and the second travelling guide ribs are respectively provided in a first edge portion and a second edge portion in width direction in an internal perimetric face of the belt body. A first joint of the first travelling guide rib and a second joint of the second travelling guide rib are disposed so as to be apart from each other in a circumferential direction of the belt body at least not less than a distance corresponding to a semicircle of an intermediate transfer belt drive roller.
Description
technical field [0001] The present invention relates to an endless belt provided with a traveling guide on either side edge, an intermediate transfer belt unit and an image forming apparatus equipped with the endless belt, and a method for manufacturing the endless belt. Background technique [0002] Conventionally, among endless belts that pass a plurality of rollers in a tensioned state, there is an endless belt adopting a configuration in which, in order to prevent the endless belt from being deviated toward the axial direction of the rollers (lateral deviation) when the rollers rotate, Travel guide members are provided on either side edge of the endless belt. [0003] For example, in the prior art, there is disclosed an image forming apparatus in which, by bonding to either side edge of the internal peripheral face of the intermediate transfer belt along the circumferential direction of the intermediate transfer belt, The thin linear rib member is used to prevent latera...
