摘要： A power transmission device includes a drive coupling, a driven coupling, and an intermediate transmission member. The drive coupling receives power from a drive source and rotates. The driven coupling is disposed coaxially on a first rotary shaft of the drive coupling and detachably attachable relative to the main body of the image forming apparatus. The intermediate transmission member meshes with the drive coupling and the driven coupling and is held by one of the drive coupling and the driven coupling in a state in which the driven coupling is disengaged from the main body. One of the drive coupling and the driven coupling, whichever holds the intermediate transmission member, constitutes a retaining coupling including an attachment member attached to one of a drive-side device and a driven-side device, and a stopper assembly facing the intermediate transmission member in an axial direction of the first rotary shaft.

摘要： A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes a position corrector and either one of a rolling body and a contact resistance reducer. The position corrector is configured to convey a sheet and correct a position of the sheet. The rolling body is disposed at least one of an upstream side and a downstream side of a sheet conveyance passage from the position corrector in a sheet conveying direction and is configured to roll in at least a direction intersecting the sheet conveying direction. The contact resistance reducer is configured to reduce contact resistance generated due to contact of the sheet to a neighboring part when the position of the sheet is corrected by the position corrector.
