摘要： A color image forming apparatus provides the prolonged life of the photosensitive drums, carrier belt, and toner of the respective colors and improves the quality of the printed color image. A carrier belt transports a recording medium placed thereon so that the recording medium passes through a plurality of printing mechanisms which print images of different colors on the recording medium in superposition. Each printing mechanism prints an image of a corresponding color. The printing mechanism is adapted to be moved into its operative position where the photosensitive drum of the printing mechanism is in contact with the carrier belt to print the image on the recording medium, and into its non-operative position where the photosensitive drum of the printing mechanism is not in contact with the carrier belt. A controller receives print data from a host device such as a personal computer and checks each page of the print data to determine whether any one of a predetermined plurality of colors is missing in the page. If a particular color is missing in the print data, then the controller outputs an UP signal to a positioning mechanism for a corresponding printing mechanism. If the color is not missing, then the controller outputs a DOWN signal. The printing mechanism moves a corresponding printing mechanism into the operative position if the UP signal is received from the controller and into its operative position if the DOWN signal is received.
摘要翻译：彩色图像形成装置提供各种颜色的感光鼓，传送带和调色剂的延长的寿命，并且提高了打印的彩色图像的质量。载体带传送放置在其上的记录介质，使得记录介质通过多个打印机构，其以叠加的方式在记录介质上打印不同颜色的图像。每个打印机构打印相应颜色的图像。打印机构适于移动到其操作位置，其中打印机构的感光鼓与传送带接触以将图像打印在记录介质上，并进入其非打印位置，其中打印的感光鼓机构不与传送带接触。控制器从诸如个人计算机的主机设备接收打印数据，并检查打印数据的每一页以确定页面中是否缺少预定多种颜色中的任何一种。如果在打印数据中缺少特定的颜色，则控制器向对应的打印机构的定位机构输出UP信号。如果颜色不丢失，则控制器输出DOWN信号。如果接收到DOWN信号，如果从控制器接收到UP信号并进入其操作位置，则打印机构将相应的打印机构移动到操作位置。

摘要： An image recording apparatus includes a rotating photosensitive drum, a developing unit, a neutralizing device, and a transferring device. An electrostatic latent image is formed on a charged surface of the rotating photosensitive drum, the electrostatic latent image being developed by a developing unit and subsequently transferred by a transferring device to a print medium. The neutralizing device neutralizes the charged surface of the photosensitive drum at the point on the surface disposed downstream of the developing unit and upstream of the transferring device with respect to rotation of the photosensitive drum. A controller controls the neutralizing device according to characteristics of the print medium such as size, material, insulation, and transparency. The neutralizing device may be operated in different modes. For example, the neutralizing device may neutralize an entirety of the charged surface of the photosensitive drum only if the print medium is of a predetermined characteristic, i.e., an insulating sheet such as a transparent OHP sheet or may neutralize only selected parts of the charged surface of the photosensitive drum according to a width of the print medium.

摘要： An electrophotographic recording apparatus that removes reverse-charged toner that is charged with a polarity opposite to a polarity of a normal-charged toner. The apparatus includes a carrier belt; a transfer roller for carrying the toner adhering to the surface of the photosensitive body toward the carrier belt; a transfer power supply for applying to the transfer roller a first voltage that causes the normal-charged toner adhering to the surface of the photosensitive body to be transferred to the recording medium on the carrier belt, and a second voltage, of opposite polarity to the first voltage, that causes the reverse-charged toner adhering to the surface of the photosensitive body to be transferred to the carrier belt; and a carrier belt cleaning blade. A control circuit controls an operation of the transfer power supply, whereby the first voltage is applied to the transfer roller during an image-forming stage, and the second voltage is applied to the transfer roller during a reverse-charged toner removing stage. For example, the normal-charged toner may have a negative polarity, the reverse-charged toner may have a positive polarity, the first voltage may be positive, and the second voltage may be negative.

摘要： An image forming apparatus includes an image-forming unit having a charging section and a developing section that are rotated together with a photoconductor in an idling manner. The charging section and developing section receive voltages while rotating. The apparatus includes a toner sensor and a controller. The toner sensor outputs a detection signal indicating that the toner has been replenished in the image-forming unit. In accordance with the detection signal, the controller changes the voltages, a time length during which the photoconductor, charging section, and developing section are rotated, or speeds at which the photoconductor, charging section, and developing section are rotated. The time length is extended or speeds are increased when the image-forming unit has been replaced.

摘要： An epitaxial silicon wafer is provided in which an epitaxial layer is grown on a silicon wafer having a plane inclined from a {110} plane of a silicon single crystal as a main surface. In the silicon wafer for growing the epitaxial layer thereon, an inclination angle azimuth of the {110} plane is in the range of 0 to 45 degrees as measured from a orientation parallel to the {110} plane toward a direction. With such an arrangement, LPDs of 100 nm or less can be measured from a {110} wafer that has a carrier mobility (including the hole and electron mobilities) higher than that of a {100 } wafer. Also, surface roughness degradation in the {110} wafer can be suppressed. Also, the surface state of the {110} wafer can be measured. Further, a quality evaluation can be performed on the {110} wafer.
