20080219717 | TRANSFER-FIXING DEVICE, IMAGE FORMING APPARATUS, AND TRANSFER-FIXING METHOD - 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. | 09-11-2008 |
20080304879 | Image forming apparatus and method of controlling same - An image forming apparatus includes a plurality of first image carriers on which different color toner images C are respectively formed, a transfer fixing member onto which a multicolor toner image A consisting of the toner images C is transferred, a heater located configured to fuse the toner image A on the transfer fixing member, a pressurizer pressing against the transfer fixing member, an image carrier located upstream of the transfer fixing member in a direction in which the recording medium is transported, on which a toner image B is formed, and a transferer facing the image carrier. The toner image A is transferred from the transfer fixing member and fixed on a recording medium in a nip formed between the transfer fixing member and the pressurizer. The toner image B is transferred from image carrier onto the recording medium before the toner image A is transferred thereonto and fixed thereon. | 12-11-2008 |

20080219718 | Transfer-fixing device, image forming apparatus including the transfer-fixing device, and transfer-fixing method - 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. | 09-11-2008 |
