摘要： 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.
摘要翻译：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。
