    • A discharge lamp with excellent arc stability and excellent durability in which the use level of thoriated tungsten is restrained has an anode and a cathode in the interior of a discharge vessel, wherein said cathode is made up from a thoriated tungsten part with a tungsten filling ratio of at least 90 vol.-% and a main body part connected to said thoriated tungsten part and consisting of pure tungsten, wherein a ratio ST/S of a side surface area ST of said thoriated tungsten part and a side surface area S of said cathode is in a range of from 0.005 to 0.15, with the proviso that, in case the cathode has a length in the direction of the cathode axis which exceeds twice the maximum diameter of the cathode, a side surface area S is used for calculating the ratio ST/S which corresponds to the side surface area where the distance along the cathode axis from a tip end adjacent to the anode is twice the maximum diameter of the cathode.
    • 具有优异的电弧稳定性和优异耐久性的放电灯,其中钍钨的使用水平被限制在放电容器的内部具有阳极和阴极,其中所述阴极由具有钨填充比的钍钨部分 至少90体积%,以及连接到所述钍钨部分并由纯钨组成的主体部分,其中所述钍钨部分的侧表面积ST和所述钍钨部分的侧表面积S的比率ST / S 阴极在0.005至0.15的范围内,条件是在阴极的长度方向上阴极轴线的长度超过阴极最大直径的两倍的情况下,侧面积S用于计算 与沿着阴极轴线距离与阳极相邻的尖端的距离为两倍于阴极最大直径的侧表面积的比率ST / S。

    • An image forming apparatus includes a developing device configured to develop an electrostatic image on an image carrier with developer, and a developer container detachably attachable to the image forming apparatus and configured to store developer to be supplied to the developing device. A developer supply unit is configured to supply the developer from the developer container to the developing device. The developer supply unit includes a developer detector configured to detect the amount of developer in the developer supply unit. The image forming apparatus controls the supply of developer transported via the developer supply unit and disables image formation on the basis of the detection result obtained from the developer detector. After the image formation is disabled, when the completion of the replacement of the developer container is detected, the image forming apparatus canceled the disabled image formation regardless of the detection result obtained from the developer detector.
    • 图像形成装置包括:显影装置,被配置为使用显影剂在图像载体上显影静电图像;以及显影剂容器,其可拆卸地附接到图像形成装置,并且构造成存储要供应到显影装置的显影剂。 显影剂供应单元构造成将显影剂从显影剂容器供应到显影装置。 显影剂供应单元包括构造成检测显影剂供应单元中的显影剂量的显影剂检测器。 图像形成装置控制通过显影剂供给单元输送的显影剂的供给,并且基于从显影剂检测器获得的检测结果来禁止图像形成。 在禁止图像形成之后,当检测到显影剂容器的更换完成时,图像形成设备取消了禁用图像形成,而不管从显影剂检测器获得的检测结果如何。
