    摘要： A fixing device includes a fixing member, a pressing member, a stationary member, a metal member, flanges, a first heater, and a second heater. The pressing member is rotatably pressed against an outer circumferential surface of the fixing member to form a nip therebetween. The metal member is fixedly disposed opposite an inner circumferential surface of the fixing member over an area other than the nip. The flanges are disposed at axial edges of the metal member in contact with an inner circumferential surface of the metal member. The first heater is disposed opposite the inner circumferential surface of the metal member to heat an axial middle portion of the metal member. The second heater is disposed opposite the inner circumferential surface of the metal member to heat axial end portions of the metal member. The first heater is disposed farther from the nip than the second heater.

    摘要： An image forming apparatus includes a fixing device, temperature detector, and a support member. The fixing device is removably installable in the image forming apparatus and includes a rotary fixing member to fuse a toner image on a recording medium, a fixing frame to support the fixing member, and an outer fixing cover provided to cover the fixing member and the fixing frame and having an opening from which a portion of a surface of the fixing member is exposed to the outside. The temperature detector is disposed opposing the fixing member to detect a temperature of the surface of the fixing member without contacting the fixing member when the fixing member is installed in the image forming apparatus. The support member supports the temperature detector to introduce the temperature detector into the inside of the fixing cover through the opening upon installation of the fixing member.

    摘要： An image forming apparatus includes an image forming part, a fixer including a heating member and a pressure member, a reverse transport part to forward a recording medium transported from the fixer to the image forming part, a toner image sensor to detect presence of a toner image on the recording medium, and a controller. When a glossy image formation mode is selected and no toner image is detected on the recording medium, the image forming part does not form a toner image on the recording medium, the fixer performs a first heating and pressing process and transports the recording medium to the reverse transport part, the reverse transport part transports the recording medium to the image forming part, the image forming part forms a toner image on the recording medium transported from the reverse transport part, and the fixer performs a second heating and pressing process and fixes the toner image thereon.

    摘要： A fixing device and image-forming apparatus, which provide required glossiness and paper adaptability, and, in addition, feature good operability and excellent durability while achieving optimal pressure-applying force for a variety of requirements, having: a pressure-applying lever; a pressure-releasing lever; a locking member, the one end of which is rotationally attached to the pressure-releasing lever; and an elastic member, which pulls the locking member in a locking direction. The configuration is such that the rotation of the pressure-releasing lever displaces the location of the locking member, thereby enabling switching between a pressure-applying position, in which a fixing member presses against another fixing member, and a pressure-releasing position, in which the one fixing member moves away from the other fixing member, and in the pressure-applying position, the pressure-applying lever and the locking member, which are fastened together at one end of the pressure-applying lever opposite a rotation central shaft, are pulled in a locking direction by the elastic member, and the gripping pressure on a piece of paper is varied by the pair of fixing members.

    摘要： A fixing device includes a fixing member, a pressing member, a heat source, and a reflecting member. The pressing member presses and contacts an outer circumferential surface of the fixing member. The heat source is disposed inside a loop of the fixing member. The reflecting member includes a reflecting portion, a pressure receiving portion, and an extending portion. The reflecting portion reflects heat toward an inner circumferential surface of the fixing member. The pressure receiving portion receives a pressing force of the pressing member via the fixing member. The extending portion extends from an area upstream to an area downstream from the nip portion in a direction of rotation of the fixing member and facing the inner circumferential surface of the fixing member. The reflecting member is in non-contact with one or more of members disposed inside the loop of the fixing member, at least when the fixing member rotates.

    摘要： A fixing device includes a rotator that rotates and a fixing device cover. The fixing device cover includes an interior face that is disposed opposite the rotator, a first aperture that is disposed opposite the rotator, and a recess that surrounds the first aperture and extends in a gravity direction. A frame is interposed between the interior face of the fixing device cover and the rotator. The frame includes a second aperture that is disposed opposite the rotator and the first aperture. A rib is mounted on the frame and extends from the second aperture toward the interior face of the fixing device cover.
