    • 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。

    • An image forming apparatus, determining in sorting recording sheets whether or not recording sheet transport interval is shorter than a first predetermined value, sets the longest time settable as a delay time when the interval is longer than the first value. When the interval is shorter than the first value, the apparatus, determining whether or not the interval is shorter than a second predetermined value, sets the shortest delay time settable when the interval is shorter than the second value, and sets a reference delay time when the interval is longer than the second value. The apparatus prevents sheet jam before a sheet eject mechanism by ensuring that the mechanism returns to an initial position before the front end of a following sheet reaches sheet eject rollers after the rear end of a preceding sheet passes through the rollers.
    • 一种图像形成装置,在分类记录片材中确定记录纸张传送间隔是否短于第一预定值时,将间隔长于第一值的最长时间设定为延迟时间。 当所述间隔小于所述第一值时,所述装置确定所述间隔是否小于第二预定值,当所述间隔小于所述第二值时,设置可设置的所述最短延迟时间,并且设置所述间隔小于所述第二值的参考延迟时间 间隔长于第二个值。 该装置通过在前一张纸的后端通过辊子之后确保在下一张纸张的前端到达纸张排出辊之前的机构返回到初始位置,防止纸张排出机构之前的纸张卡纸。

    • A fixing apparatus of the present invention is provided with (i) a roller, to which releaser gets applied (ii) a releaser applying member for applying the releaser on the roller by touching the roller while the roller is rotating, and (iii) a releaser dripping section for dripping the releaser to be applied on the roller by the releaser applying section, the fixing apparatus further including a guiding member for receiving the releaser dripped from the releaser dripping section, and for guiding, along a surface thereof, a certain amount of a total amount of the thus received releaser to a touch position at which the releaser applying member touches the roller. With this arrangement, it is possible to provide a fixing apparatus in which reduction in the amount of the releaser to be applied on the roller is avoided so as to surely prevent the toner offset and the jamming in the convey path, even if toner and/or debris is adhered, as a result of long use of the image forming apparatus, on the touch position at which the releaser applying member for applying the releaser touches the roller to which the releaser applying member applies the releaser.
    • 本发明的定影装置设置有:(i)滚子,施加释放器(ii)释放器施加部件,用于通过在滚筒旋转时接触滚筒将释放器施加在滚筒上,以及(iii) 释放器滴下部分,用于通过释放器施加部分将释放器滴落到辊上,定影装置还包括用于接收从释放器滴落部分滴落的释放器的引导部件,并且用于沿其表面引导一定量 将所接收的释放器的总量提供给释放器施加构件接触辊的触摸位置。 通过这种布置,可以提供一种定影装置,其中避免了施加在辊上的释放器的量的减少,以便即使调色剂和/或调色剂也可以确保地防止调色剂偏移和输送路径中的卡住, 或者由于长时间使用图像形成装置而在用于施加释放器的释放器施加构件接触释放器施加构件应用释放器的辊的触摸位置上粘附碎片。
