    • The delivered sheet stacking tray has a delivered sheet stacking surface, provided on an upside of an image forming section, which extends in a sheet-transporting direction so that a transporting-direction end of the delivered sheet stacking surface is opened toward a lateral outside of the image forming device body, wherein the delivered sheet stacking surface has a sheet removing concave which extends from (a) the transporting-direction end via (b) a stacking area of a maximum size sheet to (c) a stacking area of a minimum size sheet so that the sheet removing concave is positioned within an area ranging from the stacking area of the maximum size sheet to the stacking area of the minimum size sheet, and the sheet removing concave is formed substantially in parallel to a line linking (i) a corner portion of the stacking area of the maximum size sheet which corner portion is positioned on a downstream side in the transporting direction and on a front side of the image forming device to (ii) a corner portion of the stacking area of the minimum size sheet which corner portion is positioned on the downstream side in the transporting direction and on the front side of the image forming device, thereby realizing a preferable stacking condition of sheets on the delivered sheet stacking surface, and making it easy to remove the sheets.
    • 所输送的纸张堆垛托盘具有设置在图像形成部分的上侧上的输送纸张堆叠表面,该纸张堆叠表面沿纸张输送方向延伸,使得所输送的纸张堆叠表面的输送方向端朝向外侧 图像形成装置主体,其中所输送的纸张堆叠表面具有从(a)输送方向端经由(b)最大尺寸纸张的堆叠区域延伸的纸张去除凹部(c)最小尺寸纸张的堆叠区域 使得片材移除凹部位于从最大尺寸片材的堆叠区域到最小尺寸片材的堆叠区域的范围内,并且片材移除凹部基本上平行于连接(i) 最大尺寸片材的堆叠区域的角部,其角部位于输送方向的下游侧,图像形成装置的前侧, (ii)最小尺寸纸张的堆叠区域的角部,其角部位于输送方向的下游侧和图像形成装置的前侧,从而实现了在所输送的纸张上的纸张的优选堆叠条件 片材堆叠表面,并且易于去除片材。
