摘要： A fixing device includes a separator presser that presses against a plurality of separators to separate the plurality of separators from a fixing rotary body that contacts an opposed rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image passes. A single driver is connected to the separator presser to separate the separator presser from the plurality of separators. An entering recording medium detector is disposed upstream from the fixing nip in a conveyance direction of the recording medium to detect the recording medium. A controller is connected to the driver to control the driver based on a detection signal sent from the entering recording medium detector to change a contact time period for which the plurality of separators contacts the fixing rotary body.

摘要： A fixing device includes a heat conductor disposed opposite an inner circumferential surface of an endless belt to heat the endless belt. A nip formation pad is disposed opposite the inner circumferential surface of the endless belt and presses the endless belt against a pressing rotary body to form a fixing nip between the endless belt and the pressing rotary body through which a recording medium bearing a toner image is conveyed. A support is disposed opposite an inner circumferential surface of the heat conductor and contacts an abutment face of the nip formation pad to support the nip formation pad against pressure from the pressing rotary body. A heat insulator is interposed between the heater and the nip formation pad and the support to shield the nip formation pad and the support from the heater.

摘要： A fixing device includes a rotary fixing member, a counter member to contact the rotary fixing member, a first heater to heat the rotary fixing member, a driving unit to rotate the rotary fixing member, a temperature detector to detect a temperature of the rotary fixing member, and a contact-and-separation unit to switch between contact and separation states of the rotary fixing member relative to the counter member. In a temperature-raising operation, the driving unit causes the rotary fixing member to rotate when the temperature detector detects that the temperature of the rotary fixing member has reached a first setting temperature. The contact-and-separation unit causes the rotary fixing member in rotation and the counter member to contact each other when the temperature detector detects that the temperature of the rotary fixing member has reached a second setting temperature that is higher than the first setting temperature.
