Problems solved by technology

like Figure 14A and 14B As shown, in order to perform the skew control of the intermediate transfer belt 131, in the case of angularly shifting the rotation axis C-C of the belt regulating roller 135, the belt regulating roller 135 is subjected to a force in the thrust direction, and thus, due to the force in the thrust direction Friction causes wear between roller 135 and its bearings

Abstract

In case a belt member 31 of an endless intermediate transfer belt 3 causes an improper running such as a skewed or zigzag movement, the belt member 31 contacts belt contact detecting portions 70a, 70b on both ends of a belt control roller 35 and causes friction thereon. A difference in the frictional forces on the belt contact detecting portions 70a, 70b causes a pivoting of a rotary axis of the belt control roller 35 about a roller support member formed by a supporting shaft 73 and a bearing 74 at the center, thereby correcting the belt member 31 in running operation to an appropriate position.

Description

technical field [0001] The present invention relates to a device for guiding a tape, and more particularly to a tape guiding device equipped with a control mechanism for preventing the tape from skewing. The present invention also relates to a driving apparatus using a belt guiding apparatus equipped with a control mechanism for preventing belt skewing, a conveying apparatus utilizing the belt guiding apparatus, and an image forming apparatus equipped with the conveying apparatus. Background technique [0002] There is known an image forming apparatus for forming a color image that utilizes a belt drive apparatus for driving an endless flat belt called an intermediate transfer belt. In this image forming apparatus, toner images are formed on a plurality of photosensitive drums serving as image bearing members of a plurality of colors, and before the toner images are transferred onto a recording sheet, they are first transferred. printed on the intermediate transfer belt, an...
