Abstract
A fixing member used for a fixing device includes a tubular base layer; an electrode portion formed on the base layer; a heat generating portion formed on the base layer in such a manner as to be positioned next to the electrode portion in a longitudinal direction of the fixing member, the heat generating portion being electrically connected to the electrode portion; and an overcoat layer formed on the heat generating portion. The heat generating portion is a layer formed by a plurality of thin linear layers extending in the longitudinal direction of the fixing member and spaced from one another along a circumferential direction of the fixing member. The overcoat layer extends over a boundary between the heat generating portion and the electrode portion in the longitudinal direction of the fixing member.
