摘要： An apparatus for forming images on at least one surface of a sheet includes a reader for reading image information on documents, a memory for storing image signals output by the reader, and an image forming unit for selectively forming one of: (i) two page toner images corresponding to the image signals of two pages of the documents separately on two image carrying members, and (ii) a single toner image on one of the two image carrying members. A jam detector detects a jammed sheet, and a delivery detector detects delivery of a copied sheet to outside the apparatus. Image signals are eliminated from memory in accordance with a progression of image formation. If the jam detector detects the occurrence of the jammed sheet, a control unit prohibits the memory from eliminating the image signals until the delivery detector detects a next sheet delivered from the apparatus, so that the selected image expected to be formed by the image forming unit on the jammed sheet may be properly formed on a following sheet based on the image signals retained in the memory. A selector is provided for selecting one of a both-surface copy mode and a single-surface copy mode, wherein the control unit controls the memory to store the image signals corresponding to two pages of the documents when the both-surface copy mode is selected and to store the image signals corresponding to the single page of the documents when the single-surface copy mode is selected.
摘要翻译：一种用于在片材的至少一个表面上形成图像的装置包括用于读取关于文件的图像信息的读取器，用于存储由读取器输出的图像信号的存储器，以及用于选择性地形成以下各项之一的图像形成单元：（i）两页在两个图像承载构件上分别对应于两页文档的图像信号的调色剂图像，以及（ii）两个图像承载构件之一上的单个调色剂图像。卡纸检测器检测到卡住的纸张，并且传送检测器检测到复印的纸张到设备外部的传送。根据图像形成的进展，从存储器中消除图像信号。如果卡纸检测器检测到卡纸的发生，则控制单元禁止存储器消除图像信号，直到传送检测器检测到从设备传送的下一张纸张，使得期望由图像形成单元形成的所选择的图像可以基于保存在存储器中的图像信号，在卡纸上适当地形成在下一张纸上。提供选择器用于选择双面复印模式和单面复印模式中的一种，其中当选择双面复印模式时，控制单元控制存储器存储对应于两页文档的图像信号并且当选择单面复印模式时存储对应于文档单页的图像信号。
