摘要： A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and a pressure rotator to press against the fixing rotator to form a fixing nip therebetween, through which a recording medium bearing a toner image is conveyed. A rotation load applicator is coupled to one of the fixing rotator and the pressure rotator to apply a rotation load to the one of the fixing rotator and the pressure rotator. The rotation load is in a range of from 0.1 Nm to 0.6 Nm.

摘要： An image forming apparatus includes a fixing device that includes a heater to heat a fixing rotator, an opposed rotator to press against the fixing rotator to form a fixing nip therebetween, and at least one rotary body to convey a recording medium to the fixing nip. A controller rotates the fixing rotator in a forward direction to fix a toner image on the recording medium. The controller stops the heater and rotates the fixing rotator in a predetermined rotation direction when a failure occurs while the fixing device is activated. The controller determines that the predetermined rotation direction is the forward direction or a backward direction according to the at least one rotary body that sandwiches the recording medium, if the fixing nip and the at least one rotary body sandwich the recording medium simultaneously when the failure occurs while the fixing device is activated.

A contact heater is disposed at least at one lateral end of the nip formation pad in a longitudinal direction thereof and heats at least one lateral end of the endless belt in an axial direction thereof. A thermal conduction aid contacts a belt-side face of each of the nip formation pad and the contact heater and conducts heat in the axial direction of the endless belt. A cover is disposed outboard from the thermal conduction aid in a longitudinal direction thereof. The cover covers the belt-side face of the contact heater. The contact heater includes a power supply portion disposed outboard from the thermal conduction aid in the longitudinal direction thereof and covered by the cover.

摘要： A fixing device includes an endless belt formed into a loop, a heater to heat the endless belt, a nip formation assembly disposed inside the loop, and a pressure rotator to press against the nip formation assembly to form a fixing nip between the endless belt and the pressure rotator. The nip formation assembly includes a pressure pad and a supplementary thermal conductor to conduct heat from the heater in an axial direction of the endless belt. The supplementary thermal conductor has an edge portion dimensioned to distance the supplementary thermal conductor from the endless belt at an end portion of a face over which the endless belt slides in a longitudinal direction of the supplementary thermal conductor. A distance between the edge portion of the supplementary thermal conductor and the endless belt increases toward an end portion of the endless belt in the axial direction thereof.

摘要： A fixing device includes a fixing rotator and a heater disposed inside the fixing rotator to heat the fixing rotator with radiant heat. A pressure rotator presses against the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. A reflector is disposed opposite the heater to reflect the radiant heat radiated from the heater to the fixing rotator. The reflector includes a first parallel plane, a second parallel plane, and a third tilt plane. The second parallel plane is parallel to the first parallel plane and stepped with respect to the first parallel plane. The second parallel plane is disposed closer to the fixing nip and the heater than the first parallel plane. The third tilt plane bridges the first parallel plane and the second parallel plane and is disposed opposite the heater.

摘要： A nip formation assembly disposed opposite an opposed rotator via an endless belt includes a nip formation pad to press against the opposed rotator via the endless belt to form a fixing nip between the endless belt and the opposed rotator, through which a recording medium bearing a toner image is conveyed. A fixing heater is disposed opposite at least a center span of the endless belt in an axial direction thereof where the recording medium is conveyed. The fixing heater heats the endless belt. A lateral end heater is mounted on the nip formation pad and disposed opposite a lateral end span of an inner circumferential surface of the endless belt in the axial direction thereof. The lateral end heater heats the endless belt.

摘要： A fixing device includes a fixing rotator and an opposed rotator pressed against the fixing rotator to form a fixing nip therebetween. A primary heater is disposed opposite the fixing rotator in a circumferential span of the fixing rotator other than the fixing nip in a circumferential direction of the fixing rotator to heat the fixing rotator. A heat shield is interposed between the primary heater and the fixing rotator and disposed outboard from at least a decreased size recording medium conveyance span of the fixing rotator spanning in an axial direction of the fixing rotator where a recording medium having a decreased size in the axial direction of the fixing rotator is conveyed. The heat shield shields the fixing rotator from the primary heater. A secondary heater is mounted on the heat shield to heat the fixing rotator.

摘要： A sheet separating device is attached to a fixing device. The fixing device includes: a fixing member that is a rotary body having a heating unit; and a pressing member that is pressed against and is brought into contact with the fixing member. The fixing device conveys a sheet material that carries unfixed toner thereon through a nip section formed by the fixing member and the pressing member so as to fix the unfixed toner image to the sheet material. The sheet separating device includes: at least one nozzle member that discharges compressed gas from the direction of a nip outlet toward the nip section along the fixing member. The nozzle member is rotatably supported by a shaft member that is provided parallel to the fixing member and includes a gas flow passage through which compressed gas is supplied to the nozzle member.
