摘要： A developing apparatus capable of supplying a uniform thin layer of toner and of preventing toner scattering and leakage is provided, where the developing apparatus includes a supply roller for supplying toner to an outer peripheral surface of a toner carrier, the toner carrier for transferring the supplied toner by rotation and a layer thickness controlling member for controlling a thickness of the layer of the supplied toner at a predetermined value while making slide contact with the outer peripheral surface of the toner carrier via the toner, wherein the thin toner layer is supplied to an electrostatic latent image on an image carrier. The layer thickness controlling member is formed of an elastic plate to have a bent portion convex toward the toner carrier. The layer thickness controlling member is held by sealing members so that the bent portion makes elastic contact with the toner carrier outer peripheral surface over a nearly entire length of the toner carrier.

摘要： A cleaning element is arranged on the backside of the toner layer metering blade, i.e., the side opposite to the surface in contact with the developer support, in order to prevent the cleaning element from damaging the blade surface and the abutment surface of the metering blade against the developer support. This cleaning element is frictionally moved across the backside of the toner layer metering blade to remove stuck toner from the toner layer metering blade or prevent occurrence of buildups.

摘要： An electrophotography developing apparatus has been developed which can protect a developer holder and a layer thickness control member from damage. The device also prevents internal scattering of the developer while preventing a surplus supply of the developer to both ends on the peripheral surface of the developer holder. The unique advantages of the invention are derived through the utilization of sealing members having different elastic properties, which assume both bulk removal of excess developer while providing the needed uniform developer thickness. Another embodiment of the invention has the width of the layer thickness control member in a longitudinal direction set wider than the width of the developer holder in a longitudinal direction, and both side edges of the layer thickness control member are positioned outside both side edges of the developer holder. Proper sealing is assured by having the inner side edges of the sealing member positioned inside the side edges of the developer holder and outside the side edges of the image area of the image holder.

摘要： An object of the invention is to transport safely and reliably a unit such as a developing cartridge in which toner is used, and toner, and to reduce the dimensions and cost of an apparatus for packaging such a unit. Two buffer members are fixed to two opposite widthwise end sides of a developing cartridge, and the resultant combination is accommodated in a packaging box. Each buffer member has a hollow structure formed by blow molding a thermoplastic resin material. The toner is inserted into the interior of each buffer member from an opening thereof, and the buffer members and a non-toner-charged developing cartridge can be packaged together and transported. When the toner in each buffer member is supplied via the opening thereof to the interior of the developing cartridge after the transportation of these parts is completed, a structure in the developing cartridge for preventing the coagulation and leakage of the toner being transported can be simplified, and cost reduction can be effected. Since dead space in the packaging box is effectively utilized for the transportation of the toner, the safety of the transportation and a decrease in cost can be attained.

摘要： For input image data (`A`) before conversion, each pixel is converted into N (=3) parts. In this case, the three sub-pixels of data corresponding to a recording pixel (black pixel) are converted into recording sub-pixels on both sides of the three (`B`). This eliminates the density variation within a single pixel. Therefore, it is possible to reduce the dot spacing at slanted area, for example, and hence eliminate jaggies, providing a reproduced image easily recognized.
摘要翻译：对于转换前的输入图像数据（'A'），将每个像素转换为N（= 3）部分。在这种情况下，对应于记录像素（黑色像素）的三个数据子像素被转换成三（'B'）两侧的记录子像素。这消除了单个像素内的浓度变化。因此，例如可以减少倾斜区域处的点间距，从而消除锯齿状，提供容易识别的再现图像。

摘要： A developer cartridge for image forming apparatuses which performs development to form images with non-magnetic, one-component type developer. The cartridge includes a developing roller for supplying developer to a photoconductor drum, a developer feed roller in non-contact with the developing roller for supply developer to the developing roller, and a developer-layer thickness control member for controlling the thickness of the developer layer on the developing roller. The developer feed roller is shaped as a regular polygonal prism. Since no recesses are formed in the surface of the regular polygonal prism, driving torque does not increase when developer is scrubbed from the prism, thus ensuring consistent operation and improved image quality. Non-magnetic, one-component type developer is compressed onto the developing roller by supplying the developer via the developer feed roller into a bottleneck between the developing roller and a developer applying member. The amount of developer which passes through the bottleneck onto the developing roller is controlled by a temporary reservoir, the pressurization thereof ensuring application of the developer to the developing roller. A control roller may be used against the developing roller to lower friction of developer, thereby preventing deposition of developer on the control roller while establishing a consistent amount of developer on the developing roller.
摘要翻译：用于图像形成装置的显影剂盒，其用非磁性单组分型显影剂进行显影以形成图像。盒包括用于将显影剂供应到感光鼓的显影辊，与用于向显影辊供应显影剂的显影辊非接触的显影剂供给辊以及用于控制显影剂层厚度的显影剂层厚度控制部件在显影辊上。显影剂供给辊的形状为正多边形棱镜。由于在正多边形棱镜的表面没有形成凹部，所以当从棱镜上洗涤显影剂时，驱动扭矩不会增加，从而确保一致的操作和改进的图像质量。通过将显影剂通过显影剂供给辊供给到显影辊和显影剂施加构件之间的瓶颈中，非磁性的单组分型显影剂被压缩到显影辊上。通过瓶颈到显影辊上的显影剂的量由临时储存器控制，其加压确保将显影剂施加到显影辊上。可以使用控制辊抵靠显影辊以降低显影剂的摩擦，从而防止显影剂在控制辊上沉积，同时在显影辊上建立一致量的显影剂。

摘要： A developing device attachable to and detachable from a printer using a non-magnetic monocomponent developer. Two different voltages are applied respectively to a developing roller and a toner layer thickness regulating device from a power source of the apparatus main body side through a terminal and a contacting spring. A voltage is applied directly to the developing roller from the contacting spring whereas a Zener diode is provided in a path connecting the contacting spring and toner layer thickness regulating device to apply another voltage to the toner layer thickness regulating device. The voltage applied to the toner layer thickness regulating device is dropped below the power supply voltage by the Zener voltage when a low-printing-ratio image is produced. Thus, the number of the terminals connecting the apparatus main body and developing device is reduced to one. Accordingly, defective connections at the contacting portions of the terminal can be prevented and the manufacturing costs can be reduced while a satisfactory image is produced.
摘要翻译：使用非磁性单组分显影剂可附接到打印机并可拆卸的显影装置。通过端子和接触弹簧将两个不同的电压分别施加到来自设备主体侧的电源的显影辊和调色剂层厚度调节装置。电压从接触弹簧直接施加到显影辊，而齐纳二极管设置在连接接触弹簧和调色剂层厚度调节装置的路径中，以向调色剂层厚度调节装置施加另一电压。当产生低打印比图像时，施加到调色剂层厚度调节装置的电压降低到电源电压以下的齐纳电压。因此，将装置主体和显影装置连接的端子的数量减少到1个。因此，可以防止在端子的接触部分处的不良连接，并且可以在产生令人满意的图像的同时降低制造成本。
