The belt holder extends in an axial direction thereof The fuser belt is looped around the belt holder extending in the axial direction. The contact member has a central axis thereof extending in the axial direction, accommodated in the belt holder. The pressure member has a central axis thereof extending in the axial direction, disposed opposite the belt holder with the fuser belt interposed between the contact member and the pressure member. The pressure member presses against the contact member through the fuser belt to form a fixing nip. The heater is disposed adjacent to the belt holder to heat a circumferential portion of the fuser belt. The belt holder includes a generally semi-cylindrical section (S1) to face the heated circumferential portion of the fuser belt.

摘要： A toner including a binder resin, a colorant, a release agent including a paraffin wax having a melting point of from 60 to 90 °C, and an inorganic filler including a montmorillonite or modified montmorillonite. The toner has a circularity of not less than 0.94, a thermal property such that when the toner is subjected to a differentialscanning calorimetric(DSC) analysis, the endothermic quantity calculated by the endothermic peak specific to the release agent is from 3. 0 to 6. 0 J/g, and a fluidity such that when a cone-shaped rotor is entered into a toner layer by 20 mm at an entering speed of 5 mm /sec, the torque generated by the toner is from 1.4 to 2.0 mNm. A process cartridge including an image bearing member configured to bear an electrostatic image and a developing device configured to develop the electrostatic image using the toner.

摘要： A fixing device includes a tubular belt holder, a rotatable, flexible fuser belt, a heater, a fuser pad, a pressure member, and a reinforcing member. The fuser belt is looped for rotation around the belt holder. The heater is disposed adjacent to the belt holder to heat the belt holder. The fuser pad is accommodated in the belt holder inside the loop of the fuser belt, and extends in an axial direction of the belt holder. The pressure member is disposed opposite the belt holder with the fuser belt interposed between the fuser pad and the pressure member. The reinforcing member is disposed inside the loop of the fuser belt to reinforce the fuser pad under pressure from the pressure member. The fuser pad includes an elongated base, multiple longitudinally spaced protrusions, a perforated, anti-friction cover, and a fastener.

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.
