摘要： A recording media smoothness detector includes a sensor and a calculator. The sensor includes a light source to emit light toward a recording medium and a light-detecting device to detect an amount of light reflected by the recording medium. The calculator includes a first memory to store an initial output value of the sensor and a second memory to store a decreased output percentage of the sensor relative to the initial output value per number of recording media detected. The calculator is configured to calculate a decreased output amount of the sensor from the decreased output percentage of the sensor per number of recording media detected, according to number of recording media detected by the sensor, to adjust a luminosity of the sensor based on the calculated decreased output amount of the sensor and determine smoothness of the recording medium based on an output of the sensor after the adjustment.

摘要： An image forming apparatus includes a storage to store recording media, a smoothness detector to detect smoothness of the recording media, a memory unit to store smoothness values detected by the smoothness detector, a transfer device to transfer a toner image onto the recording media, a fixing device to fix the toner image onto the recording media, a temperature controller to determine a target fixing temperature for a second and subsequent recording media based on a predicted value calculated from the smoothness values, and a processor to reset the smoothness values in response to detection of an external factor that causes the smoothness detector to provide a smoothness value out of a predetermined range of the predicted value during an image forming operation from when the processor receives a sheet-feeding permission signal of one of the recording media stored in the storage until the recording medium is ejected.

摘要： A fixing device includes a fixing rotator, a pressure rotator, a cleaner, a moving assembly, and a temperature detector. The fixing rotator heats and fixes a toner image onto a recording medium. The pressure rotator presses against the fixing rotator. The cleaner contacts and cleans a cleaning target, which includes one of the fixing rotator and the pressure rotator. The moving assembly moves the cleaner between a contact position where the cleaner contacts the cleaning target and a separate position where the cleaner is apart from the cleaning target. The temperature detector detects a temperature of one of the cleaner and the cleaning target. The moving assembly moves the cleaner from the contact position to the separate position or from the separate position to the contact position during rotation of the cleaning target, in a case in which the temperature detected is greater than a given value

The pressure rotator includes an increased tackiness portion disposed at a lateral end of the pressure rotator in an axial direction of the pressure rotator to transmit a driving force to the endless belt. The increased tackiness portion is disposed opposite the thermal equalizer of the nip formation pad.

摘要： A heating device includes a first rotator, a second rotator, a heater, and a first, second and third temperature sensors. The second rotator contacts an outer circumferential surface of the first rotator to form a nip through which a recording medium passes. The heater heats the first rotator. The first temperature sensor is disposed outside a space extending from a first region through which a minimum recording medium passes and detects the temperature of the first rotator. The second temperature sensor is disposed outside the space extending from the first region and detects the temperature of the heater. The third temperature sensor is disposed outside the space extending from the first region and detects the temperature of the second rotator. At least one of the second temperature sensor or the third temperature sensor is disposed outside a space extending from a second region through which a maximum sheet passes.

摘要： An image forming apparatus includes a fixing device to fix a toner image onto a recording medium, a voltmeter to measure an input voltage from an external source, and a controller operatively connected to the fixing device and the voltmeter. The fixing device includes an endless, fixing rotator formed into a loop, a heater to heat the fixing rotator, a pressure pad disposed inside the loop, and a pressure rotator disposed opposite the pressure pad via the fixing rotator to press the fixing rotator against the pressure pad to form a fixing nip between the fixing rotator and the pressure rotator, through which the recording medium bearing the toner image is conveyed. The controller controls a heating operation of the heater and a fixing operation of the fixing device to fix the toner image onto the recording medium, based on the input voltage measured by the voltmeter.

摘要： A nip-forming member includes: a first nip-forming member configured to be a main body of the nip-forming member; and a second nip-forming member disposed on a surface of the first nip-forming member, the surface facing the inner circumferential surface, the second nip-forming member extending in a direction orthogonal to a rotating direction of the fixing belt. Both ends of the second nip-forming member on an upstream side and a downstream side of the rotating direction are bent in a direction away from the nipping part, in order to create a pair of side-wall portions, so that the second nip-forming member has a concave cross-section for accommodating the first nip-forming member. The second nip-forming member has a restraining portion at a position located on the side-wall portion created on the upstream side, the restraining portion being configured to restrain the first nip-forming member not to be detached from the concave cross-section.
