A fixing device includes a fixing rotator, a pressure rotator, a planar heater, a holder, a conductor, and a support. The pressure rotator presses the fixing rotator to form a fixing nip between the pressure rotator and the fixing rotator. The planar heater contacts an inner surface of the fixing rotator. The holder holds the heater and guides the fixing rotator. The conductor is grounded and contacts the inner surface of the fixing rotator. The support supports the holder and has a shape of regulating rotation of the conductor.

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.

A contact-separation device brings a contact-separation member into contact with a contacted member separably and includes a biasing member that generates a biasing force. A presser presses the contact-separation member against the contacted member in a pressing direction with the biasing force from the biasing member. A cam presses the presser in an opposite direction being opposite to the pressing direction. The cam is rotatable and has a cam face. A cam follower has a cam contact face that contacts the cam face of the cam. The cam contact face is curved to project toward the cam. The cam contact face has a curvature that is smaller than a greatest curvature of the cam face of the cam and is greater than a smallest curvature of the cam face of the cam.

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.

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.

Image forming apparatus

A heating device includes a housing, a heating member, a pressure member, a pair of openings, and a thermal insulator. The heating member and the pressure member extend along a longitudinal direction and press each other to form a nip portion in the housing. The heating member transfers heat to a recording medium passing through the nip portion. The pair of openings is disposed in the housing and opens facing both end portions in the longitudinal direction of the heating member so that air passes through the pair of openings. The thermal insulator is disposed inside the housing between the pair of openings and faces an outer peripheral surface of the heating member.

A contact-separation mechanism includes a cam to rotate to move a contact-separation member to and from a counterpart member, a detection target to rotate together with the cam, and a detector to detect presence or absence of the detection target in a detection area of the detector, and circuitry. The cam has a reference range. The circuitry issues a rotation stop instruction of the cam after a target time elapses from passing of the reference range of the detection target through the detection area, and sets the target time based on a duration of an immediately preceding passing of the reference range through the detection area.
