Abstract:
A fixing apparatus includes a fixing belt that is rotatable and endless, a pad, a pressing rotary member, and a scraping member. The pad contacts an inner circumferential surface of the fixing belt. The pressing rotary member contacts the pad via the fixing belt to form a nip portion. In cooperation with the fixing belt, the pressing rotary member fixes a toner image to a recording material by applying heat and pressure to the recording material at the nip portion. A lubricant is applied to the inner circumferential surface of the fixing belt. The scraping member includes an inclined portion inclined downward toward an outer side of the fixing belt and contacting an edge portion of the fixing belt to scrape the lubricant. The inclined portion is in contact with the edge portion of the fixing belt in an area where an outer surface of the fixing belt faces upward.
