摘要： A fixing device includes a nip formation pad to press against a fixing rotator. A primary heater is disposed opposite the fixing rotator in a primary heating span spanning in an axial direction of the fixing rotator to heat the primary heating span of the fixing rotator from which heat is conducted to the nip formation pad with a primary conduction. A secondary heater is disposed opposite the fixing rotator in a secondary heating span that is outboard from the primary heating span in the axial direction of the fixing rotator. The secondary heater is interposed between a first nip formation portion and a second nip formation portion of the nip formation pad to heat the secondary heating span of the fixing rotator through the nip formation pad from which heat is conducted to the fixing rotator with a secondary conduction greater than the primary conduction.

摘要： A fixing device includes a fixing rotary body rotatable in a given direction of rotation and a pressing rotary body pressed against the fixing rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A heater is disposed inside the fixing rotary body to heat the fixing rotary body. A reflector, disposed opposite an inner circumferential surface of the fixing rotary body via the heater, reflects light emitted from the heater onto the fixing rotary body. The reflector includes a movable portion movable relative to the heater to direct the light emitted from the heater onto a variable heating span of the fixing rotary body spanning in an axial direction thereof. The variable heating span varies depending on a width of the recording medium in the axial direction of the fixing rotary body.

摘要： A fixing device includes a fixing member, a nip formation member, a pressing member, and a low-friction sheet. The nip formation member is provided inside a loop formed by the fixing member rotating in a predetermined direction of rotation. The 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 low-friction sheet, over which the fixing member slides, covers the nip formation member. The nip formation member includes a first sandwiching member covered by the low-friction sheet, and a second sandwiching member sandwiching the low-friction sheet together with the first sandwiching member.
