Abstract
A transfer-fixing device transfers and fixes a toner image onto a transfer-fixing surface of a recording medium, and includes a transfer-fixing member, a pressing member, a heating member, and a temperature equalization member. The transfer-fixing member carries the toner image. The pressing member pressingly contacts the transfer-fixing member to form a nip between the pressing member and the transfer-fixing member through which the recording medium passes. The heating member heats the transfer-fixing surface of the recording medium conveyed toward the nip so that the recording medium reaches the nip before a temperature of a back surface opposite the transfer-fixing surface of the recording medium increases. The temperature equalization member equalizes temperature distribution on a surface of the transfer-fixing member in a width direction of the transfer-fixing member perpendicular to a conveyance direction of the recording medium, after the surface of the transfer-fixing member passes the nip.
