摘要： A fixing device includes a first support and a second support to rotatably support a fixing rotator at a first lateral end and a second lateral end of the fixing rotator in an axial direction thereof. A first stopper is mounted on the first support. A second stopper is mounted on the second support. A first skew restraint projects from an outer circumferential surface of the fixing rotator radially at the first lateral end of the fixing rotator in the axial direction thereof. A second skew restraint projects from the outer circumferential surface of the fixing rotator radially at the second lateral end of the fixing rotator in the axial direction thereof. The second skew restraint comes into contact with the second stopper as the fixing rotator moves in the axial direction thereof toward the first support.

摘要： A fixing device includes a fixing rotator and a pressure rotator contacting the fixing rotator to form a fixing nip therebetween, through which recording media of a plurality of sizes are conveyed. The recording media create a plurality of non-conveyance spans on a lateral end of the fixing rotator in an axial direction thereof where the recording media are not conveyed. A heater is disposed opposite the fixing rotator to heat the fixing rotator. A multi-view thermopile array is disposed opposite an outer circumferential surface of the lateral end of the fixing rotator in the axial direction thereof and angled relative to the fixing rotator to detect a temperature of the fixing rotator. The thermopile array includes an inboard temperature detection element directed to a conveyance span on the fixing rotator where the recording medium of a decreased size is conveyed.

摘要： A fixing device includes a flexible endless belt formed into a loop and having an inner circumferential surface, a heater to heat the endless belt, and a nip formation assembly disposed inside the loop formed by the endless belt. The nip formation assembly includes a pressure pad made of heat-resistant resin including a hollow filler, and a supplementary thermal conductor having a belt sliding-contact face over which the inner circumferential surface of the endless belt slides. The supplementary thermal conductor is interposed between the endless belt and the pressure pad to conduct heat from the heater in an axial direction of the endless belt. The fixing device further includes a pressure rotator to press against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the pressure rotator, through which a recording medium bearing a toner image is conveyed.

摘要： A fixing device includes an endless belt being applied with a lubricant on an inner circumferential surface of the endless belt. A pressure rotator presses against a nip formation pad via the endless belt to form a fixing nip between the endless belt and the pressure rotator. A radiant heater heats the endless belt. At least one contact heater heats at least one lateral end of the endless belt in an axial direction of the endless belt. At least one temperature detector detects a temperature of the endless belt. A controller controls the at least one contact heater to generate heat, controls the endless belt to rotate, and controls the radiant heater to generate heat sequentially based on the temperature of the endless belt that is detected by the at least one temperature detector.

摘要： An image forming apparatus includes an image forming mechanism configured to contain a developer and to form an image with the developer and a developer supplier configured to supply the developer to the image forming mechanism. The developer supplier includes a developer container, a conveyer, a sensor, an agitator, and a driver. The developer container contains the developer. The conveyer conveys the developer from the developer container to the image forming mechanism. The sensor is disposed at a predefined position on an interior wall of the developer container and detects the developer at the predefined position in the developer container. The agitator rotates to agitate the developer and includes a paddle formed in a plate-like shape and including an opening through which a part of the developer slips and avoids being paddled by the paddle. The driver drives the conveyer and the agitator at a variable speed.
