摘要： A fixing device includes a rotator, a pressure rotator, a heater, and a conductor. The pressure rotator presses the rotator to form a fixing nip between the rotator and the pressure rotator. The heater is in contact with an inner circumferential surface of the rotator and heats the rotator. The conductor is grounded and has a contact portion in contact with a center region of the inner circumferential surface of the rotator in a longitudinal direction of the rotator.

摘要： A heating device includes a pair of rotators, a heater, a temperature sensor, a conductor, a conductor support, and a component supporting the conductor. The pair of rotators is in contact with each other to form a nip through which a sheet passes. The heater heats at least one of the pair of rotators. The temperature sensor detects a temperature of the heater. The conductor has flexibility and is coupled to the temperature sensor. The conductor support supports the conductor such that a distance from the conductor to at least one position of the heater outside a predetermined region of the heater in a width direction of the sheet is larger than a distance from the conductor to a position of the heater inside the predetermined region in the width direction. The component has a first side facing the heater and a second side opposite the first side.

摘要： A fixing device includes a heat conductor disposed opposite an inner circumferential surface of an endless belt to heat the endless belt. A nip formation pad is disposed opposite the inner circumferential surface of the endless belt and presses the endless belt against a pressing rotary body to form a fixing nip between the endless belt and the pressing rotary body through which a recording medium bearing a toner image is conveyed. A support is disposed opposite an inner circumferential surface of the heat conductor and contacts an abutment face of the nip formation pad to support the nip formation pad against pressure from the pressing rotary body. A heat insulator is interposed between the heater and the nip formation pad and the support to shield the nip formation pad and the support from the heater.

摘要： A fixing device includes a fixing roller, a heat roller, an endless fixing belt wound around the two rollers to be driven to rotate, a nip forming member to form a nip while contacting the fixing belt at a position opposite the fixing roller, a pressing member to press the heat roller to separate it from the fixing roller, and a temperature detector to detect a temperature of the fixing belt at a position opposite the heat roller. The temperature detector is provided opposite or in contact with the fixing belt at a position, in parallel with the moving direction of the heat roller, on the outermost periphery of the displacement area of a surface of the fixing belt which displaces according to the approaching and departing movement of the heat roller. With such a simple structure, the temperature detector can detect the temperature of the fixing belt accurately.

摘要： A fixing device includes a fixing roller that fixes a non-fixed toner image onto a sheet, a separation roller arranged downstream of the fixing roller to separate the sheet, and an endless fixing belt wound around the fixing roller and the separation roller. A pressing roller presses against the fixing roller via the fixing belt and cooperatively fixes the non-fixed toner image with the fixing roller. A guiding member is secured to the fixing device and has a guiding hole. The guiding member guides the separation roller when the separation roller approaches or withdraws from the fixing roller along the guiding hole. A belt tensioner creates a prescribed tension on the fixing belt by applying tension use biasing force to the separation roller in an opposite direction to the fixing roller. A driving force transmitting device directly transmits rotational driving force to the separation roller via an engaging section of the separation roller. The guiding hole has an arc shape coaxially formed with the driving force transmitting device.

摘要： In a color printer in which a drive force of a fixed gear that rotates not in both a forward direction and a reverse direction but in either one direction only is transmitted to a discharging unit, a swing gear is attached to a branch guide via a switching link and a transmission link as a link mechanism. When a solenoid mechanism starts driving, the transmission link rotates. In accordance with the rotation of the transmission link, the switching link rotates, so that a switching among a discharge conveying path, a duplex-printing conveying path, and a switchback conveying path by the branch guide and a switching of a rotating direction of a transmission gear can be simultaneously performed.

摘要： An upper frame member is pivotally attached to an apparatus body so as to pivot between a closed position and an open position. The apparatus body is closed when the upper frame member is in the closed position, and the apparatus body is opened to expose an image forming unit when the upper frame member is in the open position. A locking member locks the upper frame member to the apparatus body when the upper frame member is in the closed position. An operation member positioned on a sheet stacking surface releases the locking member to unlock the upper frame member from the apparatus body.
