摘要： A transfer-fixing device includes a transfer-fixing member, a pressing member, a heating device, and a temperature equalizer. The transfer-fixing member carries the toner image. The pressing member presses against the transfer-fixing member to form a nip portion to which the recording medium is conveyed. The heating device heats the transfer-fixing surface of the recording medium conveyed toward the nip portion. The temperature equalizer equalizes a temperature distribution of a surface of the transfer-fixing member in a width direction of the transfer-fixing member after the surface of the transfer-fixing member passes through the nip portion.

摘要： 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.
