Abstract:
1. An image forming apparatus comprising: an image forming unit configured to form an image on a first sheet and a second sheet, the first sheet having a first size, the second sheet having a second size different from the first size; an ejection portion from which the first sheet and the second sheet having the image formed in the image forming unit are to be ejected; an ejection tray including a receiving portion configured to receive on a receiving surface the first sheet and the second sheet ejected from the ejection portion, the receiving portion having a first recessed portion and a second recessed portion, which are recessed downward therefrom; and a stopper portion disposed on a downstream side of the ejection tray in a sheet ejection direction further than the ejection portion, the stopper portion being configured to stop the first sheet and the second sheet ejected from the ejection portion, and the stopper portion defining a stopper projection area extending from the stopper portion to the ejection portion along the sheet ejection direction, wherein the first recessed portion and the second recessed portion are located downstream from the ejection portion and upstream from the stopper portion in the sheet ejection direction, wherein the first recessed portion and the second recessed portion are spaced apart from each other at least in the sheet ejection direction by at least a portion of the receiving surface, wherein the first recessed portion is located in a first position such that a downstream end, in the sheet ejection direction, of the first sheet completely ejected and received on the receiving surface of the ejection tray only partially covers the first recessed portion and the first recessed portion is shifted from the stopper projection area, wherein the second recessed portion is located in a second position such that a downstream end, in the sheet ejection direction, of the second sheet completely ejected and received on the receiving surface of the ejection tray only partially covers the second recessed portion and the second recessed portion is shifted from the first recessed portion at least in the sheet ejection direction, wherein the first recessed portion includes a first end and a second end spaced from each other in a width direction perpendicular to the sheet ejection direction and includes a first protrusion and a second protrusion such that the first protrusion of the first recessed portion is disposed at the first end of the first recessed portion and the second protrusion of the first recessed portion is disposed at the second end of the first recessed portion. and wherein the second recessed portion includes a first end and a second end spaced from each other in the width direction and includes a first protrusion and a second protrusion such that the first protrusion of the second recessed portion is disposed at the first end of the second recessed portion and the second protrusion of the second recessed portion is disposed at the second end of the second recessed portion.
