Abstract
An image forming system includes a sheet ejection open tray on which ejected sheets can be collected; and a sheet hold-down device including a sheet hold-down member pivotally mounted on the sheet ejection open tray via a support shaft for pivotal movement in a direction perpendicular to a surface of the sheet ejection open tray, and a hold-down member biasing device for biasing the sheet hold-down member away from the surface of the sheet ejection open tray in opposition to a weight of the sheet hold-down member itself and for maintaining a predetermined urging force of the sheet hold-down member so long as the sheet hold-down member is within a predetermined range of its pivotal movement.
