摘要： An image heating apparatus includes a flexible sleeve, a sliding member for sliding on the inner periphery of the sleeve, and a back-up member for forming a nip portion together with the sliding member through the sleeve. A recording material for bearing an image is heated while being held and conveyed by the nip portion, and a regulation member is set by facing the edge surface of the sleeve in the generatrix direction to regulate the movement of the sleeve in the generatrix direction, the regulation member having a regulation surface with which the edge surface of the sleeve contacts when the sleeve moves in the generatrix direction. The regulation surface of the regulation member has a curved-surface area in which a line when the regulation surface is cut at a virtual plane almost parallel with the nip portion is a curved line expanded toward the edge surface of the sleeve. Thereby, an image heating apparatus is provided which is able to restrain deterioration of the durability of the flexible sleeve.

摘要： There is provided an image forming apparatus that can suppress the formation of creases when forming images on both surfaces of a sheet and can greatly reduce the incidence of unprinted areas. The image forming apparatus has a sheet stacking section in which sheets are stacked, a sheet conveying section that conveys a sheet, an image forming section that forms an image on the sheet while the sheet is conveyed, a re-conveying section that again conveys the sheet with the image formed on a first surface thereof to the image forming section, and a sheet feeding section that feeds a sheet from the sheet stacking section or the re-conveying section to the image forming section. When a sheet is fed from the sheet stacking section for image formation on the first surface of the sheet by the image forming section, the sheet is fed at a first speed, and when a sheet is fed from the re-conveying section for image formation on a second surface of the sheet by the image forming section, the sheet is fed at a second speed that is slower than the first speed and is slower than the speed at which the sheet is conveyed by the sheet conveying section.
