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

摘要： A fixing device includes a first rotator and a second rotator disposed opposite the first rotator. A heater heats one of the first rotator and the second rotator. A cleaner is disposed opposite the second rotator. A temperature detector is disposed opposite the second rotator at an opposed position being within an increased conveyance span where a first sheet is conveyed and being outboard from a decreased conveyance span in an axial direction of the second rotator where a second sheet smaller than the first sheet is conveyed. The temperature detector detects a temperature of the second rotator. A mover moves the cleaner between a contact position where the cleaner contacts the surface of the second rotator and a separation position where the cleaner separates from the surface of the second rotator based on the temperature of the second rotator, that is detected by the temperature detector.

摘要： An image forming apparatus includes two rotators, a driver driving the rotators, a heating device to heat the rotator, a blower blowing air to the heating device, a temperature detector, a recording medium detector, a cover, an open-close detector, and circuitry. The circuitry detects an abnormal state and stops heat generation, determines whether the cover is closed using the open-close detector, controls the blower to blow air when the cover is closed, determines whether the recording medium is in the nip using the recording medium detector, controls the driver to rotate the two rotators when the cover is closed and no recording medium is in the nip, determines whether a temperature detected is equal to or lower than a threshold value before the cover is opened, and controls the blower to decrease an air volume when the temperature detected is equal to or lower than the threshold value.

摘要： A contact-separation device brings a contact-separation member into contact with a contacted member separably and includes a biasing member that generates a biasing force. A presser presses the contact-separation member against the contacted member in a pressing direction with the biasing force from the biasing member. A cam presses the presser in an opposite direction being opposite to the pressing direction. The cam is rotatable and has a cam face. A cam follower has a cam contact face that contacts the cam face of the cam. The cam contact face is curved to project toward the cam. The cam contact face has a curvature that is smaller than a greatest curvature of the cam face of the cam and is greater than a smallest curvature of the cam face of the cam.

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 conductivity rate and the secondary productivity rate whichever is lower as a productivity rate of the image forming apparatus.

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 first roller contacting a fixing belt to generate a rotation friction force therebetween to rotate the fixing belt and a second roller contacting the fixing belt to exert a first inhibition force to the fixing belt in a direction opposite a direction of rotation of the fixing belt. A separation aid is disposed downstream from a fixing nip formed between the fixing belt and a pressure rotator in the direction of rotation of the fixing belt to decrease a curvature of the fixing belt and exert a second inhibition force to the fixing belt in the direction opposite the direction of rotation of the fixing belt. The second inhibition force is added to the first inhibition force to obtain a combined inhibition force that is smaller than the rotation friction force between the fixing belt and the first roller.
