PROBLEM TO BE SOLVED: To provide a joint mechanism that can prevent the generation of a sound caused by the contact of shaft end faces between a drive shaft and a driven shaft, and noise attributed to static charge, and to provide a sheet feeding device having the joint mechanism and an image forming apparatus having the sheet feeding device.SOLUTION: A joint mechanism includes: a drive shaft 562 having a first shaft end face 565 and rotated by a predetermined drive source 7; a driven shaft 521 having a second shaft end face 523 facing the first shaft end face 565, and rotated to be driven by being coupled with the drive shaft 562; a coupling 62 coupling the drive shaft 562 with the driven shaft 521; and a contact prevention means 61 interposed between the first shaft end face 565 and the second end face 523 and preventing the first shaft end face 565 and the second shaft end face 523 from contacting with each other. |
