摘要： A fixing device includes a rotatable, flexible fuser belt, a heater, a fuser pad, and a pressure member. The fuser belt is looped into a generally cylindrical configuration. The heater is disposed adjacent to the fuser belt to heat the fuser belt. The fuser pad is disposed inside the loop of the fuser belt, and has an outer peripheral surface thereof formed in a generally concave configuration. The pressure member is disposed opposite the fuser pad with the fuser belt interposed between the fuser pad and the pressure member. The pressure member presses in a load direction against the outer peripheral surface of the fuser pad through the fuser belt to form a fixing nip therebetween. The fuser pad includes, along the outer peripheral surface thereof, a protruding portion and an inwardly curved portion adjoining the protruding portion to face an outer circumferential surface of the pressure member.

摘要： A fixing device includes a thermal conductor disposed inside a flexible endless fixing belt formed into a loop and configured to conduct heat from a heater to the fixing belt. The thermal conductor includes a center heating portion heated by the heater and disposed at a center of the thermal conductor in a longitudinal direction thereof orthogonal to a conveyance direction of a recording medium conveyed to the fixing belt and lateral end non-heating portions disposed at lateral ends of the thermal conductor in the longitudinal direction thereof and contiguous to the center heating portion. The center heating portion having a first diameter conducts heat from the heater to the fixing belt. The lateral end non-heating portions having a second diameter smaller than the first diameter of the center heating portion minimize conduction of heat from the heater to the fixing belt.

摘要： In a fixing device, a nip formation member is provided inside a loop formed by a fixing member rotating in a predetermined direction of rotation. A pressing member is pressed against the nip formation member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The fixing member and the pressing member rotate and convey the recording medium bearing the toner image through the nip. The heat conduction member faces an inner circumferential surface of the fixing member to guide the fixing member sliding over the heat conduction member and to transmit heat to the fixing member. The heat conduction member includes a plurality of convex portions provided on an outer circumferential surface of the heat conduction member and contacting the inner circumferential surface of the fixing member.
