摘要：
An image heating apparatus for an image forming apparatus comprises a heater and a rotary member having plasticity and rotated in contact with the heater. The rotary member in the image heating apparatus has an external shape becoming larger toward the end portions in the longitudinal direction, thereby preventing generation of wrinkles or unevenness in the conveyed recording medium.
