Fixing apparatus and electrophotographic image forming apparatus including the same

摘要

A fixing apparatus includes a heating roller and a nip forming unit facing the heating roller to form a fixing nip. The heating roller includes a resistive heating layer receiving an electric current to generate heat, and a base material supporting the resistive heating layer, wherein a resistance per unit length of the resistive heating layer at opposite sides in a length direction is less than a resistance per unit length of the resistive heating layer at a center portion.
