摘要： A fixing device includes a fixing rotary body and a heater disposed opposite the fixing rotary body. A heat shield is movable in a circumferential direction of the fixing rotary body and interposed between the heater and the fixing rotary body to shield the fixing rotary body from the heater. An overheating suppressor is interposed between the heater and the heat shield to shield the heat shield from the heater. The heat shield includes an intermediate portion spanning in the circumferential direction of the fixing rotary body and movable between a shield position where the intermediate portion is disposed opposite the heater directly and a retracted position where the intermediate portion is disposed opposite the heater via the overheating suppressor.

摘要： A fixing device includes a heat source; a fixing member looped into a generally cylindrical shape to rotate in a circumferential direction thereof and partially heated by the heat source and to heat a surface of a recording medium bearing an unfixed toner image to fix the unfixed toner image thereon in a fixing process; a rotary pressing member disposed facing the fixing member to form a nip therebetween, through which the recording medium is transported in a transport direction; and a rotation driver to rotate one of the fixing member and the pressing member. In a case in which the fixing member is halted for a reason other than the fixing process while power of the fixing device is on, electric power is not supplied to the heat source and the fixing member is rotated by a predetermined amount or more after the fixing member is halted.

摘要： An image forming apparatus includes a fixing device including a fixing rotary body and a heater for heating the fixing rotary body. An opposed body contacts the fixing rotary body with releasable pressure therebetween to form a fixing nip therebetween through which a recording medium is conveyed. A heat shield is interposed between the heater and the fixing rotary body and movable in a circumferential direction of the fixing rotary body to shield the fixing rotary body from the heater in a variable circumferential direct heating span of the fixing rotary body where the heater is disposed opposite the fixing rotary body directly. A controller halts the heat shield instantly when a fault occurs during a print job.

摘要： A pressure adjuster for changing pressure between a plurality of opposed bodies pressed against each other includes a cam rotatable in a given direction of rotation and having a top dead center on an outer circumferential surface thereof that is distanced farthest from a rotation axis of the cam. A driver is connected to the cam to drive and rotate the cam. A cam rest contacts the cam and is connected to one of the plurality of opposed bodies. A cam regulation assembly is connected to the cam to regulate rotation of the cam at least when the top dead center of the cam passes a contact position where the cam contacts the cam rest.

摘要： A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and a nip formation assembly contacting an inner circumferential surface of the fixing rotator. An opposed rotator presses against the nip formation assembly via the fixing rotator to form a fixing nip between the fixing rotator and the opposed rotator, through which a recording medium is conveyed. A support, disposed opposite the inner circumferential surface of the fixing rotator, supports the nip formation assembly. A heater, disposed opposite the inner circumferential surface of the fixing rotator, heats the fixing rotator. A reflector, disposed opposite an outer circumferential surface of the fixing rotator, reflects heat radiated from the fixing rotator onto the fixing rotator. The reflector spans a circumferential span of the fixing rotator where the fixing rotator is spaced apart from the support with a decreased interval therebetween.
