SHEET EJECTION DEVICE, AND IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide both a sheet ejection device which can convey a sheet under a situation where the width direction cross section of a sheet is deformed in a waveform and an image formation device which can eject a sheet from a sheet ejection member towards a sheet ejection board under a situation where the width direction cross section of the sheet crossing a sheet conveyance direction is deformed in a waveform.

SOLUTION: The sheet ejection device includes a plurality of first rolls prepared at separate positions far from a common axis of rotation to bear sheet ejection and a plurality of second rolls respectively corresponding to the plurality of first rolls and contacting the corresponding first rolls to bear sheet ejection together with the first rolls by pinching the sheet between the second and first rolls, wherein adjacent ones of the plurality of second rolls tilt to reverse directions mutually to have the axes of rotation crossing those of the first rolls.
