| 20110064494 | FIXING DEVICE AND IMAGE FORMING APPARATUS - A fixing device including a fixing unit that fixes a toner image on a recording material by application of heat and pressure, and a glossing unit that controls a gloss of the toner image fixed on the recording material. The glossing unit includes a heating roller, an endless belt stretched taut over multiple rollers including the heating roller, a pressing roller pressed against the heating roller with the endless belt therebetween to form a nip therebetween, and a separating member that separates the recording material from the endless belt downstream from the nip. The multiple rollers are positioned to maintain the recording material in contact with the endless belt for a predetermined distance downstream from the nip. The separating member is movable along the endless belt downstream from the nip, to control a length of contact between the recording material and the endless belt. | 03-17-2011 |

| 20110176822 | IMAGE FIXING APPARATUS STABLY CONTROLLING A FIXING TEMPERATURE, AND IMAGE FORMING APPARATUS USING THE SAME - An image forming apparatus includes an image forming mechanism and an image fixing unit. The image forming mechanism forms a toner image on a recording sheet. The image fixing unit fixes the toner image onto the recording sheet. The image fixing unit includes a magnetic flux generator, a heat member, a magnetic flux adjuster, and a controlling member. The magnetic flux generator generates a magnetic flux. The heat member is heated inductively by the magnetic flux generated by the magnetic flux generator. The magnetic flux adjuster reduces the magnetic flux active on the heat member to form a heat reduction area in an outer circumferential surface of the heat member in a width direction thereof. The controlling member moves the magnetic flux adjuster to change the heat reduction area. | 07-21-2011 |
