置。 A developing device is provided that attaches toner particles corresponding to the electrical charge on the photosensitive drum to the outer periphery of the photosensitive drum, and a transfer drum that is in line contact with the outer periphery of the photosensitive drum and rotates in synchronization with the photosensitive drum is provided, and paper that is fed from the paper feeding system is provided. In a color copying machine equipped with a transfer drum cleaner that presses a brush against the outer periphery of the transfer drum to clean it, a jam detection means is provided to detect the occurrence of a jam in the paper feed system before the transfer point. A transfer drum cleaner device for a color copying machine, characterized in that when a jam is detected by means, the operation of the copying machine is stopped, and when a copy start button is turned on after the jam is released, the transfer drum cleaner operation is omitted and a copy cycle is started. .
