    摘要: An apparatus for the formation of images comprising a transfer unit for transferring a toner image formed on a photosensitive drum onto a sheet of copy paper, a conveying unit for conveying the copy sheet in a given direction, and a shield for dividing the region below the conveying unit and transfer unit into the upper and lower portions and for shielding the photosensitive drum in the upper portion from the flow of air from the lower portion, thereby providing high quality images.

    摘要: 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.
