Abstract

An image forming apparatus of the present invention is operable in a duplex print mode for printing images on both sides of a recording medium. A toner image is transferred from a first image carrier to a second image carrier and then transferred from the second image carrier to one side of the recording medium. Subsequently, a toner image is transferred from the first image carrier to the other side of the recording medium. After the toner image has been transferred from the first image carrier to the second image carrier, the second image carrier is moved in the reverse direction to a preselected position. The apparatus of the present invention enhances productivity in the duplex print mode.
