Abstract
A copy sheet, to which a developed image has been transferred by a transfer device, continues to be attracted to a copy sheet carrying surface of an insulating film and delivered toward a fusing roller pair. A force in a direction for pressing the copy sheet toward the insulating film is exerted, by an attraction strengthening device, on the copy sheet which is passing the vicinity of a downstream end of the copy sheet carrying surface after the transfer operation. This force strengthens a force for retaining the copy sheet on the copy sheet carrying surface of the insulating film, so as to hinder a portion of the copy sheet from being bent upwardly to the side of a photoreceptor and separated from the insulating film. Thus, separation of the copy sheet from the insulating film can be prevented from extending as far as a transfer position.
