1. A fixing device comprising:
a fixing member that has an outer peripheral surface and an inner peripheral surface, is rotatably provided, comes into contact with a surface of a recording material on which an image is formed, and fixes the image to the recording material;
a rotating member that is rotatably provided and includes, at an outer peripheral portion, a contact surface coming into contact with the inner peripheral surface of the fixing member; and
a first removing member that is disposed to be in contact with the outer peripheral surface of the fixing member, is rotatably provided, and removes an attached object attached to the outer peripheral surface using a rotation speed difference with respect to the fixing member,
wherein a portion of the fixing member is deformed in an S-shape by being nipped between the first removing member and the rotating member, and the first removing member is disposed such that the portion of the fixing member is pressed against the rotating member,
wherein the rotation speed difference between the first removing member and the fixing member is caused by deformation of the fixing member into a shape in which a first portion that is a convex portion on an outer peripheral surface side of the fixing member and a second portion that is a convex portion on an inner peripheral surface side of the fixing member are continuous,
wherein the second portion is a deformation due to pressing by the first removing member at an entrance portion of the fixing member with respect to the rotating member, and
wherein a second removing member different from the first removing member is disposed at an exit portion of the fixing member with respect to the rotating member, and a portion of the fixing member is deformed in the S-shape by being nipped between the second removing member and the rotating member, and the second removing member is disposed such that the portion of the fixing member is pressed against the rotating member.
