a rotatable endless belt;
a pad configured to come in contact with an inner circumferential surface of the rotatable endless belt;
a pressing rotary member configured to come in contact with the pad via the rotatable endless belt to form a nip portion,
wherein, in cooperation with the rotatable endless belt, the pressing rotary member applies heat and pressure to a recording material which bears a toner image at the nip portion to fix the toner image to the recording material, and
wherein a lubricant is applied to the inner circumferential surface of the rotatable endless belt; and
a scraping member configured to scrape the lubricant by being in contact with an edge portion of the rotatable endless belt in a width direction,
