摘要：
A transfer-fixing device (66) includes a transfer-fixing member (27), a pressing member (68), a heating device (67), and a temperature equalizer (85). 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.
