<p><P>PROBLEM TO BE SOLVED: To provide a nipping structure for a paper sheet and an image forming device equipped with it capable of preventing the sheet from wrinkling or hopping up in the nipping part. <P>SOLUTION: The image forming device 10 is equipped with a transcription part 40 furnished with a transcription belt 42 to transport a paper sheet P2 on which a toner image is transcribed through a photo-sensitive drum 41, a fixation roller 51 and a pressurizing roller 52 installed adjoiningly at the downstream end of the transcription belt 42 of this transcription part 40 in such a way as forming a pair up and down and forming the nipping part 53 to nip the sheet P2, and a guide member 70 installed between the downstream end of the belt 42 and the nipping part 53 and guiding the sheet P2 from the transcription part 40 to the fixation part 50. The fixation roller 51 is shaped in an inverted crown in which the diameter decreases gradually from each end toward the center, while the guide member 70 is shaped in a crown such that its edge confronting the nipping part 53 is positioned mating with the inverted crown shape. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
