<p>PURPOSE:To obtain an inexpensive and simple structured device which keeps stabilized sheet conveyance and the image not disturbed by arranging a pair of conveying rotors so as to constantly hold a sheet between at least two pairs of conveying rotors along the sheet conveying direction. CONSTITUTION:This image forming device is provided with image forming means 3 to 6, which form image on a sheet 10, and a plural number of conveying rotor pairs 101, 102, which convey, by sandwiching the sheet 10 between them, on which an image is formed by means of the image forming means 3 to 6. In such an image forming device pairs of conveying rotors 101, 102 are arranged so as to sandwich the sheet 10 constantly between at least two pairs of conveying rotors 101, 102 along the sheet conveying direction. For instance, plural number of conveying rotor pairs 101, 102 are arranged so as to sandwich the sheet 10 between the rolls at the side edge portion of the sheet 10. Or further, at least one pair of conveying rotors 101, 102 can be made changeable either to a condition of sandwiching the sheet 10 between the rotors or to a condition of not being able to sandwich the sheet 10 between the rotors because of the rotors being separated from each other.</p> |
