Abstract:
1. A fusing unit to fuse an image to a recording medium by applying heat and pressure to the recording medium, the fusing unit comprising: a heating member to heat the recording medium; and a pressurizing member to apply pressure to the recording medium, wherein the heating member is divided into a paper-contact heating region contacting the recording medium and a paper non-contact heating region not contacting the recording medium, and a heating value per unit area of the paper-contact heating region is different from a heating value per unit area of the paper non-contact heating region, the heating member comprising a heating layer to generate heat to enable heating of the recording medium, the heating layer comprising polyimide containing carbon nanotubes (CNTs), and a mixture ratio between the polyimide and the CNTs in the paper-contact heating region and a mixture ratio between the polyimide and the CNTs in the paper non-contact heating region is different.
