Abstract:
An image forming apparatus is provided, which forms a releasing agent absorption toner image on an in-between printed sides area of a moving surface of an image carrier in the duplex printing mode. When the in-between printed sides area of the moving surface enters a transfer position at which a toner image is transferred from the image carrier to a recording medium, the transferring operation of transferring the toner image from the image carrier to a recording medium is interrupted to keep the releasing agent absorption toner image on the in-between printed sides area of the moving surface of the image carrier.
