ABSTRACT:
A transfer fixation apparatus includes: a fixing member that carries the toner image; a pressurizing member that becomes in contact with the fixing member with pressure to form a nip through which the recording target medium is transported; and a plurality of heating members that are provided at relatively upstream positions when viewed from the relatively downstream nip and apply heat to the surface of the recording target medium that is transported toward the nip, wherein the number of heating members that apply heat to the surface of the recording target medium is changed depending on whether the transfer of the toner image is performed only on the front side of the recording target medium or the transfer of the toner image is performed also on the reverse side of the recording target medium after the transfer of the toner image on the front side of the recording target medium.
