摘要： A developing apparatus contains a developer for developing a latent image formed on an image carrier. The developing apparatus includes a developer carrier disposed opposite to the image carrier; a developer regulating member regulating an amount of the developer carried by the developer carrier; and a developer circulating unit transporting the developer in a circulating path. The developer circulating unit includes a rotatable first transport member supplying the developer to the developer carrier while transporting the developer in a horizontal direction, a shielding member preventing the developer separated from the developer carrier from flowing back toward the first transport member, and a rotatable second transport member collecting the developer separated from the developer carrier while transporting the developer in the horizontal direction. A distance between the second transport member and the developer carrier is greater than a distance between the first transport member and the developer carrier.

摘要： A development device is operable in multiple different speed modes and includes a developer bearer to carry developer, a developer regulator to adjust an amount of developer carried on the developer bearer, and multiple developer conveyance members disposed facing the developer bearer to transport developer in a longitudinal direction to circulate developer inside the development device. The multiple developer conveyance members including a first developer conveyance member to supply developer to the developer bearer and a second developer conveyance member to transport developer collected from the developer bearer. The development device executes developer amount balance adjustment in which a driving velocity of at least the multiple developer conveyance members is increased from a driving velocity in a lower-speed mode for a predetermined period after image development in the lower speed mode is completed and before image development in a higher speed mode is started.

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
