Abstract
A fusing unit and a fusing apparatus using the fusing unit are provided. The fusing unit includes a pipe-shaped fusing roller having a heat generating unit and electrode members at both ends thereof. A power supply unit contacts the electrode members and supplies current thereto. A blocking member is disposed between the electrode members and the power supply units to block current by separating the power supply unit from the electrode members when a temperature of the heat generating unit rapidly increases.
