摘要： A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and a nip formation pad disposed inside the fixing rotator. A pressure rotator presses against the nip formation pad via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. A heat generator is disposed inside the fixing rotator to heat the fixing rotator. A reflector is interposed between the heat generator and the nip formation pad. The reflector includes a reflection face to reflect radiant heat radiated from the heat generator. The reflection face includes a reflection portion disposed opposite the heat generator at various angles. A support is provided separately from the nip formation pad and supports the reflector.

摘要： A fixing device includes a first heater and a second heater disposed inside a fixing rotator to heat the fixing rotator. The first heater generates an increased amount of heat and includes a first heat generator having a first heating span in a longitudinal direction of the first heater. The second heater generates a decreased amount of heat and includes a second heat generator having a second heating span in a longitudinal direction of the second heater. A partition is interposed between the first heater and the second heater to define a first compartment having an increased size and accommodating the first heater and a second compartment having a decreased size and accommodating the second heater.

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 fixing device includes a fixing rotary body, an opposed member opposing the fixing rotary body to form a nipping portion, and a heater to heat the fixing rotary body. The heater includes heat generators arranged in a width direction of a recording medium and separately supplied with power. When an unfixed image on the medium has an image area and a non-image area, power supplied to each of the heat generators is controlled so that, of the heat generators, a first heat generator corresponding to the image area becomes a higher temperature and second heat generators corresponding to the non-image area becomes a lower temperature. When the second heat generators are adjacent to each other, power supplied to one of the second heat generators closer to the image area is set to be greater than power supplied to another of the second heat generators farther from the image area.

摘要： A fixing device includes a rotatable fixing member to rotate while contacting an unfixed image; a pressure member to form a fixing nip with the fixing member; a heating member having a plurality of heating elements divided in a direction perpendicular to a conveyance direction of a sheet; a heat performance sensor to detect heating performance of each heating element of the heating member, and a controller to control the heating member. The controller controls each heating element independently such that a temperature of a portion of the fixing member corresponding to a blank area becomes lower than the temperature of a portion of the fixing member corresponding to an image area; and controls the temperature to be maintained at each heating element based on the detection result of the heating performance of each heating element detected by the heat performance sensor.

摘要： Power is supplied from a capacitor of an auxiliary power source to a secondary heating element of a heating unit, thereby preventing temperature drop of a fixing roller at the time of continuous paper delivery. An allowable range for starting discharge from the capacitor is set to, for example, 30 to 40 volts. A discharge time in which the voltage of the capacitor reduces to a termination value, such as 20 volts, is longer than a time necessary for a reading unit to read a maximum number (for example, 100 sheets) of documents that can be read at one time.
