Abstract

PURPOSE: To perform high-speed and large volume copying without abandoning unnecessary transfer paper by subjecting the transfer member of the copying machine to required processing according to the jam occuring conveying region.
CONSTITUTION: Secondary latent images are transferred onto the conveying member being conveyed by a regist roller by an insulation drum 7 formed with the secondary latent images. The driving of motors for conveying, etc. is stopped according to the jam detection by the jam detectors 60W63 in the transfer region thereof. In this case, the motor for driving the second conveying region provided with a fixing device 13, etc. on the transfer belt through this conveying path does not stop unless there is the jam detection by jam detectors 64W67 and the transfer member in this conveying path is supplied to a tray 14, sorter 18, etc. without being discharged. Hence, only the minimum transfer members are abandoned at the occurrence of jam.
