    摘要： A transfer fixing device includes a transfer fixing member, a pressure member, and a primary heater. The transfer fixing member defines a moving surface on which a toner image travels. The pressure member is pressed against the transfer fixing member to define a transfer fixing nip where the toner image traveling along the moving surface meets a surface of a recording medium traveling along the media conveyance path. The primary heater is located upstream of the transfer fixing nip along the media conveyance path to heat the surface of the recording medium before entering the transfer fixing nip. The heated surface of the recording medium fuses toner for transfer and fixing into place at the transfer fixing nip. The pressure member is at least partially electrically biased to generate an electrostatic field to promote transfer of toner at the transfer fixing nip.

    摘要： In a transfer-fixing device for transferring and fixing a toner image on a transfer-fixing side of a recording medium, a transfer-fixing member carries the toner image. A pressing member presses against the transfer-fixing member to form a nip between the transfer-fixing member and the pressing member through which the recording medium passes. A heat transmission member is provided upstream from the nip in a recording medium conveyance direction to heat the transfer-fixing side of the recording medium while guiding the recording medium to the nip. A heating member is connected to the heat transmission member to heat the heat transmission member. A biasing member biases the recording medium guided by the heat transmission member against the heat transmission member.
