摘要： An image forming apparatus includes a fixing belt stretched across a first roller and a second roller including an elastic layer. A pressure rotator presses against the second roller via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A recording medium bearing a toner image is conveyed through the fixing nip. A clearance detector detects a clearance between the first roller and the second roller. A mover moves the pressure rotator with respect to the second roller in a pressing direction in which the pressure rotator presses against the second roller via the fixing belt and a separation direction in which the pressure rotator separates from the second roller. A controller controls an amount of movement of the pressure rotator moved by the mover toward the second roller based on the clearance detected by the clearance detector.

摘要： An image forming apparatus includes a fixing rotator rotatable in a predetermined direction of rotation, over which a recording medium is conveyed, and a heater to heat the fixing rotator. A temperature detector detects a temperature of the fixing rotator. A controller performs a primary productivity control to define a primary productivity rate of printing per unit time based on the temperature of the fixing rotator that is detected by the temperature detector. The controller calculates an amount of power suppliable to the heater and performs a secondary productivity control simultaneously with and separately from the primary productivity control. The secondary productivity control defines a secondary productivity rate of printing per unit time based on the amount of power suppliable to the heater. The controller selects one of the primary productivity rate and the secondary productivity rate whichever is lower as a productivity rate of the image forming apparatus.

摘要： A fixing device includes a heater, a fixing rotator, a pressure rotator to press against the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which a recording medium is conveyed, a moving device to move the pressure rotator in directions in which the pressure rotator comes into contact with and separates from the fixing rotator, a thermal expansion amount predictor to predict an amount of thermal expansion of the fixing rotator while the recording medium is conveyed, and a nip width adjuster to control a moving distance of the pressure rotator moved by the moving device toward the fixing rotator, depending on the amount of thermal expansion of the fixing rotator predicted by the thermal expansion amount predictor, so as to adjust a width of the fixing nip to maintain a substantially constant width of the fixing nip.

摘要： A drive transmission unit transmits driving force to a driven unit including a driven rotator coupled to the drive transmission unit via a unit coupler. The drive transmission unit includes a driving source, a drive transmission member to transmit driving force from the driving source to the driven rotator by engaging the driven rotator, and a basal plate with a turning shaft portion at one end thereof. The basal plate supports the driving source and the drive transmission member thereon. The drive transmission unit is turned around the turning shaft portion together with the driven unit in a direction substantially orthogonal to a direction of a driving reaction force applied to the drive transmission member when the driven rotator receives the driving force from the drive transmission member.

摘要： A fixing device includes a fixing rotator, a pressure rotator, a cleaner, and a moving assembly. 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 at which the cleaner contacts the cleaning target and a separate position at which the cleaner is apart from the cleaning target. The moving assembly includes a biasing member that presses the cleaner to move to the contact position. The moving assembly moves the cleaner from the contact position to the separate position against a biasing force of the biasing member. The moving assembly moves the cleaner from the separate position to the contact position while increasing and then decreasing the biasing force of the biasing member greater than the biasing force applied when the cleaner is located at the contact position.

摘要： A fixing device, corresponding to a plurality of sheet passing widths, includes a rotating member configured to convey a recording medium, rise in temperature, and fix toner; temperature sensors configured to detect the surface temperature of the rotating member; heating members including at least one heat generating unit, provided inside the rotating member; and a control unit configured to control a heating state obtained by the heating members. The heat generating units are provided not to overlap each other in the direction of the sheet passing width orthogonal to the recording medium conveying direction. The temperature sensors are only placed at positions corresponding to the heat generating units used when printing on the recording medium having a minimum width. The control unit controls the heating state in accordance with the surface temperature, a sheet passing width, and an operational state of the rotating member that changes with time.
