摘要： A heating device includes a heating rotator, a pressure rotator, a planar heater, and a holder. The pressure rotator is configured to press against the fixing rotator to form a nip through which the recording medium is conveyed. The planar heater includes a plurality of heat generators arranged side by side and at least one separation region between the plurality of heat generators. The holder holds the planar heater and contacts the planar heater in a pressure direction in which the pressure rotator presses the heating rotator. The holder includes at least one clearance structure configured to cause a contact area between the planar heater and a portion of the holder corresponding to the at least one separation region to be smaller than a contact area between the planar heater and a portion of the holder not corresponding to the at least one separation region.

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： 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 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 removable unit that is attachable to and detachable from a body of an apparatus includes a positioning projection and an upstream projection. The positioning projection projects downward to position a unit or a member located below the removable unit when the removable unit is attached to the body. The upstream projection projects more downward than the positioning projection at an upstream end of the removable unit in an attachment direction of the removable unit to the apparatus. A lower end of the positioning projection is located higher than a line connecting a lower end of the upstream projection and a lower portion of a downstream end of the removable unit in the attachment direction when viewed in a direction orthogonal to both an up and down direction and the attachment direction.
