Abstract
A heating member includes: a resistive heating layer including: a medium-passing area, and non-medium-passing areas respectively on opposing sides of the medium-passing area at opposing side portions of the resistive heating layer; a core which supports the resistive heating layer; a thermally conductive layer between the resistive heating layer and the core, and disposed in a non-medium passing area at a side portion of the resistive heating layer; and an electrode which is between the resistive heating layer and the core, contacts the side portion of the resistive heating layer and supplies current to the resistive heating layer. A ratio of a contact area between the thermally conductive layer and the resistive heating layer to an area of the non-medium-passing area in which the thermally conductive layer is disposed, ranges from about 5% to about 25%.
