A fixing device includes a rotatable pressing roller, a fixing rotator to rotate in contact with the pressing roller, a nip formation pad, and a slide sheet disposed between the nip formation pad and the fixing rotator. The slide sheet includes a base material layer made of a woven fabric of spun yarn. In the base material layer, a distance between adjacent spun yarns is equal to or less than 0.4 times a width of the spun yarn in a cross-section of the slide sheet in a direction of slide movement of the fixing rotator, and, in a cross-section of the slide sheet in a longitudinal direction of the slide sheet and a direction perpendicular to the slide movement of the fixing rotator, a thickness of the spun yarn is equal to or greater than 0.2 times a width of the spun yarn.

In a fixing device, a fixing member contacts an opposing member to form a nip therebetween through which a recording medium bearing a toner image passes. A plurality of separators provided downstream from the nip in a recording medium conveyance direction contacts the fixing member to separate the recording medium having passed between the fixing member and the opposing member from the fixing member. A plurality of contact-direction biasing members connected to the plurality of separators biases the separators to cause the separators to contact the fixing member. A releasing member contacts the separators to cause the separators to separate from the fixing member. A driver connected to the releasing member separates the releasing member from the separators to cause the separators to contact the fixing member.

In a fixing device, at least one separator is provided downstream from a fixing nip formed between a fixing rotary member and a pressing rotary member in a recording medium conveyance direction to contact the fixing rotary member to separate a recording medium having passed through the fixing nip from the fixing rotary member. A feeler is provided upstream from the fixing nip in the recording medium conveyance direction and contacted by the recording medium conveyed toward the fixing nip to receive a pushing force from the recording medium. A transmission assembly is connected between the feeler and the separator to receive and transmit the pushing force to the separator to move the separator from a non-contact position at which the separator does not contact the fixing rotary member to a contact position at which the separator contacts the fixing rotary member.

A toner agitating unit is located in a toner hopper that houses toner used for developing a latent image. The toner agitating unit includes a rotary shaft and an agitating member. The agitating member is a flat plate made of resin. The agitating member has a plurality of slits extending from an outer edge of the agitating member toward the rotary shaft.

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.

A fixing device includes a pair of first frames that support an axis of each of a fixing roller and a pressing roller and a pair of second frames arranged in parallel to an axial direction of the fixing roller to connect the first frames to each other. The second frames include cover portions that cover an upper peripheral surface and a lower peripheral surface of the rollers. A coupling member couples the cover portions to each other and has a bridge structure between the cover portions.
