Abstract

A sheet member discharge mechanism comprising an upper discharge roller and a lower discharge roller for conveying a sheet member in a predetermined direction while nipping it therebetween. A push-down member is disposed downstream of the nipping portion between the upper discharge roller and the lower discharge roller as viewed in a direction of conveying the sheet member, the push-down member being allowed to move between an ascended position and a descended position and is urged to the descended position. The push-down member is moved to the ascended position by the sheet member acting upon the push-down member while the sheet member is being conveyed by the upper discharge roller and the lower discharge roller that work in cooperation. The push-down member moves to the descended position to push down the trailing edge of the sheet member after the trailing edge of the sheet member has passed the nipping portion between the upper discharge roller and the lower discharge roller.
