摘要： A nip forming device includes an endless belt that is flexible and rotates and a nip former that is disposed opposite an inner circumferential face of the endless belt. A pressure rotator presses against the nip former via the endless belt to form a nip between the endless belt and the pressure rotator, through which a conveyed object is conveyed. A separator is disposed downstream from the nip in a conveyance direction of the conveyed object. The separator separates the conveyed object from the endless belt. The separator includes a non-contact portion separated from the endless belt and a contact portion that contacts the endless belt. The contact portion retains a gap having a predetermined size between the non-contact portion and the endless belt.

摘要： A fixing device includes a first rotator, a second rotator, a heater, a nip formation pad, and a separator. The second rotator contacts an outer circumferential surface of the first rotator to form a nip between the first rotator and the second rotator. The heater includes a resistive heat generator to heat the first rotator. The nip formation pad contacts an inner circumferential surface of the first rotator to form the nip. The separator separates a recording medium passing through the nip from the first rotator. The separator includes a separating surface and a contact. The separating surface is separated from the outer circumferential surface of the first rotator and separates the recording medium from the first rotator. The contact contacts the outer circumferential surface of the first rotator at a position where the first rotator is pinchable between the contact and the nip formation pad.

摘要： A nip forming device includes an endless film and a pressure rotator that presses against a heater via the endless film. A driver drives and rotates the pressure rotator to cause the pressure rotator to drive and rotate the endless film. A controller controls the driver to drive and rotate the pressure rotator, based on a temperature of the pressure rotator, that is detected by a detector, in a forward direction to convey a conveyed object and to interrupt forward rotation of the pressure rotator. In response to a determination that the temperature of the pressure rotator is higher than a predetermined temperature when a job of the nip forming device is finished, the controller controls the driver to drive and rotate the pressure rotator for a predetermined time in a backward direction opposite to the forward direction and to interrupt backward rotation of the pressure rotator.

摘要： A fixing device includes a rotator, a secured member, a pressure rotator, and lubricant. The rotator has flexibility and a sleeve form. The rotator includes an inner portion having a sliding surface. The inner portion has an elastic power of 55% or more. The secured member is disposed inside a loop of the rotator and has a slide surface on which the sliding surface of the rotator slides. The slide surface has a larger hardness than a hardness of the sliding surface of the rotator. The pressure rotator presses the rotator against the secured member and forms a nip between the rotator and the pressure rotator. The lubricant is provided between the rotator and the secured member.

The rotator includes an inner portion having a sliding surface. The inner portion has an elastic power of 55% or more. The secured member is disposed inside a loop of the rotator and has a slide surface on which the sliding surface of the rotator is to slide. The slide surface has a smaller surface roughness in a sliding direction of the rotator than a surface roughness of the sliding surface in the sliding direction of the rotator. The pressure rotator presses the rotator against the secured member and forms a nip between the rotator and the pressure rotator. The lubricant is provided between the rotator and the secured member.

摘要： A fixing device includes an endless fixing rotator, a heater, a nip formation pad, and a pressure rotator. The heater is disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator. The nip formation pad is disposed opposite the inner circumferential surface of the fixing rotator that is slidable over the nip formation pad. The pressure rotator is configured to press against the nip formation pad via the fixing rotator to form a fixing nip through which a recording medium bearing a toner image is conveyed while being sandwiched between the fixing rotator and the pressure rotator. The nip formation pad includes a base and a thermal equalizer having a thermal conductivity higher than a thermal conductivity of the base. The nip formation pad has a nip face opposite the fixing nip. The thermal equalizer is disposed in at least part of the nip face.

摘要： A fixing device includes a fixing rotator and a pressure rotator that is disposed opposite the fixing rotator. A nip former is disposed inside a loop formed by the fixing rotator and disposed opposite the pressure rotator via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. The fixing rotator slides over the nip former. A flange supports the fixing rotator at both lateral ends of the fixing rotator in a longitudinal direction of the fixing rotator. The nip former includes a base and a thermal conductor that has a thermal conductivity greater than a thermal conductivity of the base. The base is greater than the thermal conductor in the longitudinal direction of the fixing rotator. The base includes a groove that is disposed outboard at least from the thermal conductor in the longitudinal direction of the fixing rotator.
