摘要： A particle beam generator has a vacuum chamber, a magnet which generates a constant magnetic field in the vacuum chamber, acceleration electrodes which generates a magnetic field in a direction perpendicular to the direction of the magnetic field generated by the magnet in the vacuum chamber, a take-out electrode which takes out charged particles accelerated in the vacuum chamber; and a target cell provided at a position at which the charged particles taken out by the taken-out electrode strikes. At least a part of surfaces exposed to the charged particles of the vacuum chamber, the acceleration electrodes, the take-out electrode and/or the target cell is made of a material including an element having atomic number larger than copper.

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.
