摘要： A fixing device includes a fixing rotator, a pressure rotator, a heat source, a nip formation pad, and a support. The nip formation pad presses against the pressure rotator to form a fixing nip between the fixing rotator and the pressure rotator. The support supports the nip formation pad toward the fixing nip. A longitudinal end portion of the pressure rotator has an outer diameter greater than that of a longitudinal center portion of the pressure rotator. The pressure rotator includes a grip that contacts the nip formation pad via the fixing rotator outside a recording medium with a maximum width conveyable passing through the fixing nip and applies a frictional force to the fixing rotator. The nip formation pad includes a nip face having an inflection point from which a longitudinal direction of the nip face is curved toward the support within an area opposite the grip.

摘要： A fixing device includes a fixing rotator and a pressure rotator that is disposed opposite the fixing rotator. A nip former is disposed inside a loop formed by the fixing rotator and disposed opposite the pressure rotator via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. The fixing rotator slides over the nip former. A flange supports the fixing rotator at both lateral ends of the fixing rotator in a longitudinal direction of the fixing rotator. The nip former includes a base and a thermal conductor that has a thermal conductivity greater than a thermal conductivity of the base. The base is greater than the thermal conductor in the longitudinal direction of the fixing rotator. The base includes a groove that is disposed outboard at least from the thermal conductor in the longitudinal direction of the fixing rotator.

摘要： A fixing device may include an endless fixing member; a heating unit that is provided inside an inner peripheral surface of the fixing member; and a nip forming unit that comes into press-contact with a rotationally driven pressing member with the fixing member interposed therebetween to form a nip. The nip forming unit has a shape in which a center of a contact surface protrudes toward the pressing member compared to both ends. The nip forming unit has a protruding amount at a center toward the pressing member compared to both ends of the nip forming unit in no-load state is set to be less than a bent amount of the nip forming unit when the nip forming unit comes into press-contact with the pressing member with the fixing member interposed therebetween.

摘要： A fixing device includes 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 is operatively connected to the heater and the heat shield to move the heat shield after the controller turns on the heater as a print job starts so as to change an area of the direct heating span of the fixing rotary body.
