摘要： A sheet ejection tray on which a sheet ejected from a sheet ejection port lands, includes: an inclined surface that becomes higher as farther from the sheet ejection port in a sheet ejecting direction; a projecting member that is provided in a region closer to the sheet ejection port than the position on which a leading end of the sheet having a dimension not smaller than a predetermined value lands and which has a guiding surface more inclined than the inclined surface; and an abutting cover that contacts a rear end of the sheet moving toward the sheet ejection port due to the inclination of the guiding surface. The leading end of the sheet passes above the projecting member before landing on the guiding surface. A portion of the sheet closer to the sheet ejection port than the leading end lands on the guiding surface.
