摘要： A fixing device includes an endless belt and a pressure rotator disposed opposite an outer circumferential surface of the endless belt. The pressure rotator has a first span in an axial direction of the endless belt. A nip formation pad, which is disposed opposite an inner circumferential surface of the endless belt, forms a fixing nip between the endless belt and the pressure rotator. The nip formation pad includes a belt-side face disposed opposite the endless belt. A radiant heater, which is disposed opposite the inner circumferential surface of the endless belt, heats the endless belt. A thermal conduction aid, which contacts the belt-side face of the nip formation pad, conducts heat in the axial direction of the endless belt. The thermal conduction aid has a second span within which the first span of the pressure rotator is provided at the fixing nip.

摘要： A fixing device includes a lateral end heater, disposed opposite a lateral end of an inner circumferential surface of a fixing rotator in an axial direction thereof, to heat the fixing rotator and a thermal conduction aid contacting the fixing rotator and the lateral end heater to conduct heat. The lateral end heater includes a power supply portion disposed outboard from a lateral end of the thermal conduction aid in a longitudinal direction thereof and disposed opposite the inner circumferential surface of the fixing rotator. The power supply portion includes an electrode. A cover covers the power supply portion and includes a cover face disposed opposite the inner circumferential surface of the fixing rotator. A height adjuster adjusts a height of the cover face of the cover and causes the cover face to define an identical plane with a fixing rotator side face of the thermal conduction aid.

摘要： A fixing device includes a heat generator being disposed inside a loop formed by a rotator and including a heat generating portion to radiate radiant heat. A reflector is disposed inside the loop formed by the rotator and includes a reflection face to reflect the radiant heat radiated from the heat generator toward the rotator. A support supports the reflector. A holder holds each lateral end of the support in a longitudinal direction of the support, which is perpendicular to the rotation direction of the rotator. A fastener attaches the reflector to the support at an attachment position disposed at each lateral end of the reflector in a longitudinal direction of the reflector. The attachment position is disposed outboard from a lateral edge of the heat generating portion of the heat generator and disposed inboard from the holder in the longitudinal direction of the reflector.

摘要： A fixing device includes a primary heater disposed opposite a fixing rotator to heat a circumferential span of the fixing rotator other than a fixing nip formed between the fixing rotator and a pressure rotator and a secondary heater disposed outboard from the primary heater in an axial direction of the fixing rotator to heat the fixing rotator at the fixing nip. The primary heater and the secondary heater heat a bi-heating span of the fixing rotator in the axial direction thereof. The secondary heater heats a mono-heating span of the fixing rotator in the axial direction thereof and generates a decreased amount of heat to be conducted to the bi-heating span of the fixing rotator. The decreased amount of heat is smaller than an increased amount of heat to be conducted to the mono-heating span of the fixing rotator that is heated by the secondary heater only.

摘要： A fixing device includes fixing rotator, a heater to heat the fixing rotator, a pressure rotator disposed opposite an outer circumferential surface of the fixing rotator, a pressure pad disposed opposite an inner circumferential surface of the fixing rotator, a support to support the pressure pad, and a thermal conduction aid to conduct heat in an axial direction of the fixing rotator. The pressure pad presses against the pressure rotator via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. The pressure pad includes a nip-side face disposed opposite the inner circumferential surface of the fixing rotator. The thermal conduction aid covers the nip-side face of the pressure pad. The nip-side face of the pressure pad includes at least one mouth therein defining a non-contact area in which the pressure pad does not contact the thermal conduction aid.

摘要： An image forming apparatus includes an image forming device to form a toner image on a recording medium under a prescribed image forming condition, a fixing device to fix the toner image borne on the recording medium thereonto by heating the recording medium based on target fixing temperature, and a detector to detect a type of recording medium. The type is used in setting at least one of the image forming condition and the target fixing temperature. The inequality Tb>Ta is established when Ta represents a time period needed to reach a setting of fixing temperature allocated to the recording medium with its tip detected by the detector after detection of the tip and Tb represents a time period needed for the recording medium with its tip detected by the detector to reach the fixing device after detection of the tip.

摘要： A transfer-fixing device includes a transfer-fixing member, a pressing member, a heating device, and a temperature equalizer. The transfer-fixing member carries the toner image. The pressing member presses against the transfer-fixing member to form a nip portion to which the recording medium is conveyed. The heating device heats the transfer-fixing surface of the recording medium conveyed toward the nip portion. The temperature equalizer equalizes a temperature distribution of a surface of the transfer-fixing member in a width direction of the transfer-fixing member after the surface of the transfer-fixing member passes through the nip portion.
