Problems solved by technology

[0004] In addition, the idle roller (53) is supported on the arm (63) which is rotatably supported on the belt frame (61), and not only due to the spring for applying tension to the transfer belt (51) ( 59) and due to the rotation of the arm (63), once the idler roller (53) passes its dead point, the idler roller (53) cannot return to its original position, thus making it difficult to stabilize the serpentine operation of the idler roller (53) correction

Abstract

The invention discloses an endless member drive apparatus and an image forming apparatus. The endless member drive apparatus includes: an endless member that has plane surfaces and rotates by receiving a drive force; a drive support member that supports and drives the endless member; a rotatable support member that includes a rotation shaft, and that supports the endless member; a portion to be positioned; a bearing member that includes: a bearing portion that supports the rotatable support member rotatably, and that supports the rotatable support member in such a manner that the rotatable support member can be moved in an intersecting direction to intersect a tensile direction wherein a tensile force is generated in the endless member; and a positioning portion that positions the rotatable support member, wherein the bearing member has a hole portion, the position portion has an inclining surface which goes outwardly in the axial direction and radial direction, and moves and positions the rotatable support member by using a force applied to the rotatable support member along the intersecting direction, in a case where the endless member is rotated.

Description

technical field [0001] The present invention relates to an annular member driving device and an image forming device. Background technique [0002] As technologies related to conventional image forming apparatuses including ring-shaped members, technologies respectively disclosed in the following patent documents are known. [0003] In JP-A-2006-162659 (the term "JP-A" used here means "Unexamined Published Japanese Patent Application"), there is disclosed a technology regarding the structure: The pulley (57) that is in contact with the belt edge (58) of (51) is rotatably supported on the end of the idler roller (53), and is provided with a tiltable roller tilting lever (64), which roll tilting lever (64 ) is used to support the rotating shaft of the idler roller (53) and may also be in contact with the pulley (57). In this structure, when the transfer belt (51) is deflected, the belt edge (58) presses the pulley (57) so that the roller tilt lever (64) in contact with the p...
