摘要： A fixing device includes a fixing rotator, a pressure rotator, a pressure plate, a pressing force adjuster, an entrance guide, an exit guide, and a guide. The pressure rotator presses the fixing rotator to form a nip between the fixing rotator and the pressure rotator. The pressure plate rotates about a fulcrum to press the pressure rotator. The pressing force adjuster adjusts a pressing force of the pressure rotator. The entrance guide guides a recording medium entering the nip. The exit guide guides the recording medium ejected from the nip. The guide guides the pressure rotator in a direction inclined from a line connecting a rotation center of the fixing rotator and a rotation center of the pressure rotator toward downstream in a conveyance direction of the recording medium.

摘要： A fixing device includes a heater, a heating rotator, a nip formation rotator, and an entry guide. The entry guide guides each of a first recording medium having a predetermined length or more and a second recording medium having a length less than the predetermined length to the fixing nip. The entry guide includes a first and second entry guide portion. The first entry guide portion guides the first recording medium toward a harder one of the heating rotator and the nip formation rotator and has an opening. The second entry guide portion guides the second recording passing through the opening to the fixing nip along a reference line connecting an entry and exit of the fixing nip or guides the second recording medium from an area including a softer one of the heating rotator and the nip formation rotator with respect to the reference line to the fixing nip.

摘要： An image forming apparatus includes two rotators, a driver driving the rotators, a heating device to heat the rotator, a blower blowing air to the heating device, a temperature detector, a recording medium detector, a cover, an open-close detector, and circuitry. The circuitry detects an abnormal state and stops heat generation, determines whether the cover is closed using the open-close detector, controls the blower to blow air when the cover is closed, determines whether the recording medium is in the nip using the recording medium detector, controls the driver to rotate the two rotators when the cover is closed and no recording medium is in the nip, determines whether a temperature detected is equal to or lower than a threshold value before the cover is opened, and controls the blower to decrease an air volume when the temperature detected is equal to or lower than the threshold value.
