Abstract: A fixing apparatus includes a fixing belt, a pressure roller, a heater, a stay holder, and a scraper. The fixing belt is configured to heat an image on a sheet at a nip portion and has an inner surface with a grease applied thereon. The pressure roller drives and rotates the fixing belt and forms the nip portion between the pressure roller and the fixing belt. The heater and the stay holder press the fixing belt toward the pressure roller from the inner surface of the fixing belt. The scraper scrapes the lubricant transferred to the pressure roller in an area that can come into contact with the fixing belt and that does not come into contact with a maximum width sheet introducible into the fixing apparatus on one end side in a rotational axis direction of the pressure roller.

Abstract: A fixing unit includes an endless belt, a heating unit configured to heat the belt, a pressure rotary member configured to form a fixing nip portion that nips and conveys a recording material with the belt, a pad configured to press the belt toward the pressure rotary member, a sliding sheet provided on the pad and configured to slide against the belt, a plate-like member configured to fix the sliding sheet to the pad, the sliding sheet being fixed in a manner sandwiched between the plate-like member and the pad, and fixing tools configured to fix the plate-like member at a plurality of positions along a longitudinal direction of the plate-like member. A width of the sliding sheet is wider than a width of the fixing nip portion and narrower than a width of the plate-like member in the longitudinal direction.

Abstract: An image heating apparatus includes a controller configured to control a temperature at which energization to a heater is turned off, depending on a detection temperature of a detecting portion, wherein, when a temperature rise rate per unit time of the detection temperature of the detecting portion is a first rise rate, the controller turns off the energization to the heater in response to the detection temperature reaching a first temperature, and, when the temperature rise rate per unit time is a second rise rate that is less than the first rise rate, the controller turns off the energization to the heater in response to the detection temperature reaching a second temperature that is greater than the first temperature.

Abstract: An image forming apparatus that sets a second conveyance speed, at which a recording material is conveyed at a heating nip portion, higher than a first conveyance speed, at which the recording material is conveyed at a transfer nip portion, conveys an envelope by the transfer and heating nip portions without transferring a toner image at the transfer nip portion. After that, the image forming apparatus which sets the second conveyance speed equal to or lower than the first conveyance speed transfers the toner image formed on a photosensitive drum acting as an image bearing member onto the envelope conveyed again to the transfer nip portion by a reversing conveyance mechanism acting as a re-conveyance unit to fix the toner image on the envelop at the heating nip portion.

Abstract: An image heating apparatus includes an endless belt, a rotary member configured to form a nip portion with the endless belt, regulating members for regulating the endless belt from moving in a longitudinal direction by being in contact with longitudinal ends of the endless belt, and a sheet-like heating member. The heating member includes a heat transfer member in contact with the inner surface of the endless belt, and a heating portion located on an opposite side from a side, of the heating member, in contact with the inner surface of the endless belt across the heat transfer member. Both end portions of the heat transfer member are disposed at the same location or outside of both end portions of the heating portion in the longitudinal direction and are disposed inside of both end portions of the rotary member in the longitudinal direction.
