    • Either a single copy or a plurality of copies of an original document may be made. Making a single copy or the last copy of a plurality of copies comprises, during a first revolution of a photoconductive drum, electrostatically charging the drum, radiating a light image of the document onto the drum to form an electrostatic image, developing the electrostatic image using a magnetic brush to form a toner image, transferring the toner image to a copy sheet, electrostatically discharging the drum and uniformly radiating the drum with light to further discharge the same. During a second revolution of the drum the drum is cleaned with the same magnetic brush to remove residual toner, and again electrostatically discharged and uniformly radiated. During a third revolution of the drum the magnetic brush is again used for cleaning. For making all but the last of a plurality of copies, the drum is charged, imaged, transferred and electrostatically discharged during a first revolution thereof and cleaned with the magnetic bruch during a second revolution. Whether the process is used to make one or more copies, the same portion of the drum is always used. Subsequently, the drum rotation is indexed so that the next process will use a different portion of the drum.
    • 可以进行单个副本或原件的多个副本。 制作单个副本或多份副本的最后一个副本包括在感光鼓的第一次旋转期间,静电对该鼓进行充电,将原稿的光图像照射到滚筒上以形成静电图像,使用 磁刷以形成调色剂图像,将调色剂图像转印到复印纸上,静电放电滚筒并用光均匀地辐射滚筒以进一步对其进行放电。 在滚筒的第二次旋转期间,用相同的磁刷清洁滚筒以除去残留的调色剂,并再次静电放电并均匀地辐射。 在滚筒的第三次旋转期间,磁刷再次用于清洁。 为了制作多个副本中的最后一个,鼓在其第一次旋转期间被充电,成像,传送和静电排出,并且在第二次旋转期间用磁性布擦洗。 无论该过程是用于制作一个或多个副本,始终使用鼓的相同部分。 随后,滚筒旋转被转位,使得下一个处理将使用滚筒的不同部分。

    • An image forming apparatus which forms an image on a recording medium at a number of different dot densities. The image forming apparatus includes a light source part for emitting a light beam, a light detection part for detecting a light beam from the light detection part detecting a light beam from the light source part and for supplying a signal indicative of a power of the detected light beam when a monitored voltage obtained by the light beam is approximately equal to a reference voltage, a memory part for storing a number of power data corresponding to the number of different dot densities, an input part for inputting a first dot density selected, a power data control part for supplying a signal indicative of a changed power data which is changed from a value of said power of the detected light beam with a power data stored in the memory means which is located by the selected first dot density, and a driving part for operating the light source with the signal from the power data control part allowing the light source to emit a light beam with the changed power, the changed power being appropriate for forming an image on the recording medium at the selected first dot density.

    • Timing pulses (TP) are generated in response to incremental rotation of a photoconductive drum (40). The pulses (TP) are counted by a presettable counter (10) and decoded to produce control signals (STEP.sub.n) for scanning of an original document, sheet feed and other operations. When the count in the counter (10) reaches a certain value, the counter (10) is preset to a value depending on the paper size. A single control program is provided having a sequence of fixed program steps which are executed in response to respective counts in the counter (10). The smaller paper lengths are accommodated by programably presetting the counter (10) in such a manner as to skip unnecessary count sequences.
    • 定时脉冲(TP)响应于感光鼓(40)的增量旋转而产生。 通过预设计数器(10)对脉冲(TP)进行计数,并对其进行解码以产生用于扫描原始文件,送纸和其它操作的控制信号(STEPn)。 当计数器(10)中的计数达到一定值时,计数器(10)根据纸张尺寸预设为一个值。 提供具有响应于计数器(10)中的相应计数而被执行的固定程序步骤序列的单个控制程序。 通过可编程地预设计数器(10)来容纳较小的纸张长度,以便跳过不必要的计数序列。
