| titleOfInvention | Fixing device and image forming apparatus using the same |
| abstract | In an electrophotographic image forming apparatus, toner to be used is charged with positive or negative static electricity. For example, when fixing with a heat fixing device using a heating member and a pressure member, the heating member directly contacting the toner is used. Hot offset is likely to occur, in which unfixed toner on the recording medium adheres electrostatically and reversely transfers to the recording medium again. There is a method for preventing toner adhesion by applying a direct current bias having the same polarity as the electrostatic polarity of the unfixed toner to the heating member, but a power source for that purpose must be provided. The present invention prevents hot offset without using a special power source. By selecting the material of the heating member and the pressure member, particularly the volume resistance value, to have a specific relationship, the surface potential due to static electricity generated in each member when driving both members is represented by X, When Y [V] is set and the difference value X−Y = Z [V] is determined, Z is set to have the same polarity as the electrostatic polarity of the unfixed toner.
