ABSTRACT:
The transfer-fixing device includes an image carrier, a pressing member, a heater, and an electrical field generator. The image carrier carries a toner image. The pressing member presses against the image carrier to form a transfer-fixing nip between the pressing member and the image carrier. The heater heats the toner image carried by the image carrier so that a temperature of the toner image is not higher than Tm +10 degrees centigrade when a toner softening point is Tm degrees centigrade. The electrical field generator forms a transfer electrical field at the transfer-fixing nip.
