Abstract:
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.
