摘要： A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and an opposed rotator disposed opposite the fixing rotator to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A heater is disposed opposite the fixing rotator to heat the fixing rotator. A nip formation pad is disposed opposite an inner circumferential surface of the fixing rotator. The nip formation pad includes a base, a first thermal conductor sandwiched between the base and the fixing rotator and having a first thermal conductivity greater than a thermal conductivity of the base, and a bulge projecting from the first thermal conductor toward the opposed rotator at a downstream end of the first thermal conductor in a recording medium conveyance direction.

摘要： A fixing device includes a fixing rotary body, a heat shield movably disposed opposite the fixing rotary body, an opposed body contacting the fixing rotary body to form a nip therebetween through which a recording medium is conveyed, and a temperature detector to detect a temperature of at least one of the fixing rotary body and the opposed body. A controller, operatively connected to the heat shield and the temperature detector, determines a rotation angled position to which the heat shield is moved based on a size of the recording medium and the temperature of the at least one of the fixing rotary body and the opposed body detected by the temperature detector.

摘要： A fixing unit includes a fixing member, a pressing member, a heating device, a sheet width detector, and a heating area adjustor. The pressing member faces the fixing member to form a fixing nip between the fixing member. An un-fixed toner image is fixed on a recording medium when the recording medium passes through the fixing nip. The heating device heats the fixing member while maintaining a non-contact condition with the fixing member. The sheet width detector detects sheet width of the recording medium. The heating area adjustor changes a heating area of the fixing member, heatable by the heating device, based on the sheet width detected by the sheet width detector. The heating area adjustor is moveable in a space between the fixing member and the heating device along a sheet width direction to change a size of the heating area.

摘要： A fixing device includes a fixing rotator, an opposing rotator, a temperature detector, and a support. The fixing rotator has a hollow and heats an image to fix the image onto a recording medium. The opposing rotator forms a fixing nip between the fixing rotator and the opposing rotator. The temperature detector includes an exposed conductive portion. The support has conductivity and is disposed in the hollow of the fixing rotator to support the fixing rotator at the fixing nip. The support has at least one of a recessed portion or an opening at a position facing the exposed conductive portion of the temperature detector.

摘要： An image forming apparatus includes a heating device including a rotator member, a heating member configured to heat the rotator member. The heating member is switchable between a first heat generation state in which an amount of heat generated on a first side is larger than an amount of heat generated on a second side in the intersection direction and a second heat generation state in which the amount of heat generated on the second side is larger than the amount of heat generated on the first side, The image forming apparatus is configured to switch between the first heat generation state and the second heat generation state while executing a job of continuously forming an image on a plurality of recording media having a same length in the intersecting direction.

摘要： A heating device includes a rotator, an opposed rotator configured to contact the rotator to form a nip, a heater configured to heat the rotator, and a plurality of pressing devices. The heater includes a first portion and a second portion. The second portion of the heater generates a larger amount of heat than the first portion of the heater. The pressing devices are arranged in a longitudinal direction of the heater and each configured to press at least one of the rotator and the opposed rotator and cause the rotator and the opposed rotator to press each other. The pressing devices include a first pressing device corresponding to the first portion of the heater and a second pressing device corresponding to the second portion of the heater, and the first pressing device generates a smaller pressing force than the second pressing device.

摘要： A fixing device includes an endless belt-shaped fixing member, a rotary pressing member disposed opposite the fixing member, a stationary member, a friction reducer, and a activation device. The endless belt-shaped fixing member formed in a loop moves in a predetermined direction and fixes a toner image on a recording medium by heating and fusing the toner image. The stationary member is provided inside the loop and pressed against the rotary pressing member through the fixing member to form a nip between the rotary pressing member and the fixing member through which the recording medium bearing the toner image passes. The friction reducer disposed between the fixing member and the stationary member reduces friction generated therebetween. The activation device provided inside the loop of the fixing member moves the friction reducer to change a portion of the friction reducer that comes between the fixing member and the stationary member.
