SHEET CONVEYANCE DEVICE AND INK JET TYPE IMAGE FORMATION APPARATUS HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sheet conveyance device and the like which suppress re-transfer of ink to a sheet by making a linear pressure acting on a nip part fall within a constant range.SOLUTION: A sheet conveyance device 20 comprises: a plurality of drive rollers 30 which are rotatably provided around a shaft in a second conveyance path 16 or the like where a sheet S is conveyed; a plurality of driven rollers 35 which form a plurality of nip parts 38 by being brought into pressure-contact with a peripheral surface of each drive roller 30; and a plurality of pressure mechanisms 26 which press each driven roller 35 to each drive roller 30. The respective pressure mechanisms 26 have pressing forces F1, F2 set in accordance with the axial lengths of each drive roller 30 and each driven roller 35 so that linear pressures P1, P2 acting on the respective nip parts 38 fall within the constant range.SELECTED DRAWING: Figure 2
