Sheet conveying apparatus and image forming apparatus

摘要

A sheet conveying apparatus has a conveying rotating member, a follower rotating member which is disposed to face the conveying rotating member, a support member which passes through a hollow portion of the follower rotating member and supports the follower rotating member, a pressure portion which biases the support member toward the conveying rotating member so that the follower rotating member comes into contact with the conveying rotating member a first bearing portion which is disposed between an outer peripheral surface of the support member and an inner peripheral surface of the follower rotating member and rotatable supports the follower rotating member with respect to the support member, and a second bearing portion which movably supports the support member and has a slide friction coefficient higher than that of the bearing portion.

1. A sheet conveying apparatus comprising:
a conveying rotating member which is rotatably driven by a driving portion and conveys a sheet; a cylindrical follower rotating member which is disposed to face the conveying rotating member; a support member which passes through a hollow portion of the follower rotating member and supports the follower rotating member; a pressure portion which biases the support member toward the conveying rotating member so that the follower rotating member comes into contact with the conveying rotating member; a first bearing portion which is disposed between an outer peripheral surface of the support member and an inner peripheral surface of the follower rotating member and rotatably supports the follower rotating member with respect to the support member; and a second bearing portion which movably supports the support member and has a slide friction coefficient higher than that of the first bearing portion.
