Heating member and fusing device including the same

A heating member comprising:

• a resistive heating layer comprising:
• a medium-passing area,
• non-medium-passing areas respectively on opposing sides of the medium-passing area at opposing side portions of the resistive heating layer, and
• electrode contact areas respectively at the opposing side portions of the resistive heating layer, and opposing the medium-passing area with respect to the non-medium-passing areas;
• a core which supports the resistive heating layer;
• and
• an electrode which is between the core and the resistive heating layer, supplies current to the resistive heating layer, and respectively contacts a side portion of the resistive heating layer, wherein the electrode comprises:
• a contact portion which contacts an electrode contact area at the side portion of the resistive heating layer, and
• a thermally conductive portion which extends from the contact portion, is between the core and the resistive heating layer, and contacts a non-medium-passing area at the side portion of the resistive heating layer.
