Abstract
An overlapped-transfer preventing paper supply device in an image-forming apparatus includes an overlapped-transfer preventing member and a rotary paper supply member in an overlapped-transfer preventing portion. A sheet-returning member returns a sheet located in the vicinity of the overlapped-transfer preventing portion to a sheet source or supply and moves from a downstream side to an upstream side of the overlapped-transfer preventing portion. A drive operates in response to a sheet-returning signal to move the sheet-returning member in a sheet-returning direction. A sheet located in the vicinity of the overlapped-transfer preventing portion can be prevented from being damaged, and jamming due to such sheet can be prevented.
