Abstract
A polarity inverting charger is provided at the location between developing position of a photoconductor and transfer position to invert the polarity of a toner image formed on the photoconductor after a first image is transferred onto an intermediate transfer belt from the photoconductor. A transfer charger is actuated with opposite polarity to that of the polarity when the first toner image is transferred onto the intermediate transfer belt to transfer the first toner image on the intermediate transfer belt onto a second surface of a transfer sheet simultaneously when a polarity inverted second image on the photoconductor is transferred onto a first surface of the transfer sheet.
