Abstract An image forming apparatus for forming a toner image on a recording material. The image forming apparatus includes an image forming portion to form the toner image on the recording material, and a fixing portion to fix, at a nip, the toner image on the recording material by feeding and heating the recording material on which the toner image is formed. The fixing portion includes a roller having an outer surface that has electroconductivity, a rotatable member that forms the nip and is in contact with the roller, and a casing having electroconductivity. An electrical insulating member is positioned (i) nearest to the outer surface of the roller, and (ii) between the inner surface of the casing and the outer surface of the roller. The electrical insulating member does not directly or indirectly contact the outer surface of the roller, and is provided with a water-absorbing member.
