An image forming apparatus includes a transport unit, a transfer unit and a support unit. The transport unit transports a recording medium. The transfer unit transfers an image formed with particles onto an image formation surface of the recording medium transported by the transport unit by an electric field formed between the transfer unit and the image formation surface by making contact with the image formation surface. The support unit supports the recording medium, is transported to the transfer unit together with the recording medium by the transport unit, and is not directly conductive with the transfer unit.
