PURPOSE: To prevent the occurrence of offset of a transcribed picture to a guide means or the like, by giving a half-fixing process to the transcribed picture with heating.

CONSTITUTION: A heating process is applied via the reflecting cover 42 to the toner image that is transcribed from the photosensitive drum 1 to the trnasfer paper 201 via the transcriber/electrifier 25 or the like. Thus the toner image receives a fused half-fixing process with such a degree that causes no offset. As a result, no offset of the transcribed picture is caused to the inducting guide rollers 37 and others of the subsequent guide maens.
