摘要： An image forming apparatus includes a transport member that transports a recording medium, an image carrier that carries a toner image, a transfer member that transfers the toner image onto the recording medium, a fixing device that fixes the toner image, a reversing path that reverses the recording medium, and a controller. When the toner image is a borderless image and there is a burr on an edge portion of the recording medium, the controller controls the transport member, the image carrier, and the transfer member so that the recording medium passes between the image carrier and the transfer member and through the fixing device without the toner image being transferred onto the recording medium, and then the recording medium is transported along the reversing path to between the image carrier and the transfer member and the toner image is transferred onto the recording medium.

摘要： An image forming apparatus includes a first forming unit that forms a color image on a first image-carrier using a color toner, a first transfer unit that transfers the color image formed on the first image-carrier to a transfer medium at a first transfer bias, a second forming unit that, using an invisible toner absorbing infrared light or ultraviolet light, forms on a second image-carrier a code image representing information by an arrangement of dots, and a second transfer unit that transfers the code image formed on the second image-carrier to the transfer medium at a second transfer bias higher than the first transfer bias.
