ABSTRACT:
A transfer-printing sheet separating system including a device for bending the leading end portion of a transfer-printing sheet having a pair of rotary members interposed between a sheet feeding device and a transfer-printing station near the periphery of a photosensitive member and disposed on opposite sides of the path of travel of the transfer-printing sheet, and a separating member disposed downstream of the transfer-printing station with respect to the direction of travel of the transfer-printing sheet and having a forward end spaced apart from the periphery of the photosensitive member a predetermined distance. The transfer-printing sheet has its leading end portion bent or curved before being fed to the transfer-printing station, and separated from the periphery of the photosensitive member by the separating member after a toner image is printed thereon. Rotation of the rotary members may be temporarily stopped or a pair of registration rollers may be used for obtaining registration of the leading end of the transfer-printing sheet with the leading end of the toner image on the periphery of the photosensitive image at the transfer-printing station.
