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 rotary body and a pressing rotary body disposed opposite the fixing rotary body. A pivotable pressurization member contacts and presses the pressing rotary body against the fixing rotary body. A pressurization pivot is provided on the pressurization member. A depressurization member, pivotable about the pressurization pivot, causes the pressurization member to isolate the pressing rotary body from the fixing rotary body. A depressurization pivot is provided on the depressurization member. A lock is pivotable about the depressurization pivot and engageable with the pressurization pivot. A biasing member, anchored to the lock, exerts a resilient bias that allows the lock to cause the pressurization member to press the pressing rotary body against the fixing rotary body. A detent is situated in a pivotal trajectory of the lock to restrict pivot of the lock by contacting the lock.

摘要： An image forming apparatus includes multiple image forming units each accommodating an image bearer and a developer bearer to develop a latent image formed on the image bearer. Each of the image forming units other than a prescribed image forming unit runs in an ordinary reverse rotation mode, in which at least one of the image bearer and the developer bearer rotates in an opposite direction during a non-image formation time period. The prescribed image forming unit runs in a special reverse rotation mode, in which at least one of the image bearer and the developer bearer rotates in the opposite direction during the non-image formation time period based on a differentiated one of a rotation time period, a start timing, a rotational speed, and a frequency of operation from those of the other image forming units, or does not run in the special reverse rotation mode.

摘要： A conveying device conveys a sheet of non-blank recording medium recorded with an image formed in an image forming unit, and includes a container that is detachable and contains a sheet of blank recording medium, a feeding unit that feeds the blank recording medium from the container, and a recirculating path that leads the non-blank recording medium to the feeding unit. The recirculating path is disposed lateral to the image forming unit. A part of the recirculating path is integrated into the container and forms a reversing path that leads to the feeding unit. At least one of surfaces of the reversing path can be exposed.

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.
