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.

摘要： A fixing device includes a fixing rotator heated by a heater and a pressing rotator to press against the fixing rotator to form a fixing nip therebetween. A heating span adjuster, interposed between the heater and the fixing rotator, is movable in a circumferential direction of the fixing rotator. The heating span adjuster moves to a retracted position where the heating span adjuster allows the heater to heat the fixing rotator in an increased axial heating span of the fixing rotator after the heater starts heating the fixing rotator until the fixing rotator and the pressing rotator start conveying a recording medium through the fixing nip. The heating span adjuster at the retracted position is outboard from a circumferential, direct heating span of the fixing rotator where the heater heats the fixing rotator directly.

摘要： A waste-toner collecting device includes a waste toner collector that collects and stores therein non-transferred toner as waste toner conveyed from a cleaning unit via the conveying path; and a leveling member that levels waste toner accumulated inside the waste toner collector, and drive of which is controlled so that driving conditions thereof are varied based on information of an image formed on the image carrier. The switching of the driving conditions of the leveling member is controlled so as to be performed after a delay time during which the non-transferred toner collected in the cleaning unit reaches the waste-toner collector via the conveying path.
