摘要： An inverting document feeder feeds a document from the document tray to the position where the image reader reads the document, turns the document over, and then reads the second side. Document size determination sensors detects the document passing through, and determines the size of the document from detections signals of the width of the document and the time elapsed between the detection of the top end of the document and the detection of the bottom end of the document. When the top end of the document reaches the document reading position, image reading is started by a scanner, regardless of whether the document size has been determined or not. The image data thus obtained are written into and read out of a memory unit in a specified order. Even if the document reading has not been finished at the time of determining the document size, feeding of a copying sheet of a size corresponding to the document size is started, and the image data stored in the memory unit are read out to form an image on the copying sheet.

摘要： When it is judged that a sheet S is not an ordinary paper but a thick paper or an OHP film sheet, or that the arrival of the sheet S at a pair of timing rollers 48 is delayed due to a slip for example beyond an allowable period of time, a controller 70 judges that a condition for transferring or fixing an image on the sheet S is not met. As a result, a secondary transfer roller 34 and a cleaner 38 are retreated from an intermediate transfer belt 12, and in this state, the intermediate transfer belt 12 carrying a toner image I thereon is made idle at least about one revolution without transferring the image I.

摘要： The recording sheet supporting surface of the transport belt comes in contact with the photosensitive drums for cyan, magenta, yellow, and black in the color copy mode, and is separated from the photosensitive drums aside from the photosensitive drum used for forming a black image in the monochrome copy mode with the image forming units for cyan, magenta, and yellow not being activated. With this separating operation, the distance on the transportation path of the recording sheet measured from the synchronizing roller to the transfer position of the photosensitive drum used for forming a black image in the monochrome copy mode is longer than in the color copy mode. Thus, the start time of scanning the surface of the photosensitive drum used for forming the black image is delayed in the monochrome mode according to the difference in distances between the color and monochrome modes.
