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： 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 a fixing rotator and at least one heater, disposed opposite an inner circumferential surface of the fixing rotator, to heat the fixing rotator. The at least one heater includes a heat generator to generate heat. A lateral end heater is disposed at least at one lateral end of a nip formation pad in a longitudinal direction of the nip formation pad. The lateral end heater heats at least one lateral end of the fixing rotator in an axial direction of the fixing rotator. The lateral end heater includes a base, a resistor, mounted on the base, to generate heat, and an electrode coupled to the resistor to supply power to the resistor. The electrode is disposed outboard from the heat generator of the at least one heater in the axial direction of the fixing rotator.

摘要： A fixing device includes a fixing rotator formed into a loop and rotatable in a predetermined direction of rotation and a pressure rotator disposed outside the loop formed by the fixing rotator and pressed against the fixing rotator to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A stay is disposed opposite the pressure rotator via the fixing rotator. A heater is disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator. A pressurization member is pressed against the heater via the fixing rotator. A housing is interposed between the stay and the heater. A temperature detector is mounted on the housing to detect a temperature of the heater.

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.
