Abstract
A copying machine with a multiple transport function having a separation charger for separating from the photoreceptor surface copy paper with an image transferred thereon and a circulating transport passage formed from the paper discharge block to the paper feed block so that it is possible to select the single-sided copy mode for allowing the copy paper to be discharged outside the copying machine after the copying process, the duplex copy mode for allowing the copy paper undergoing one copying process to be led through the circulating transport passage to the copying process block as reversed, or the composite copy mode for allowing the copy paper undergoing one copying process to be led through the circulating transport passage to the copying process block without being reversed. The copying machine with a multiple transport function includes a current controller which sets current applied to the separation charger for the second copying process at a larger value in the composite copy mode and at a smaller value in the duplex copy mode than that for the copying process in the single-sided copy mode.
