Abstract: PROBLEM TO BE SOLVED: To suppress image defect caused by opposite-polarity toner, to maintain a normal image forming operation, and to ensure satisfactory image quality and the life of each means even in long-term use. SOLUTION: The fixing device 14 has a fixing roller 31 which is in contact with an unfixed image formed of toner 93 on a recording material 91, and a pressure roller 32 pressure welded to the fixing roller 31. The fixing device 14 fixes the unfixed image on the recording material 91 to the recording material 91 by conveying the recording material 91 with the fixing roller 31 and the pressure roller 32 while gripping the recording material 91 between them. The fixing device 14 applies a holding electric field in the direction in which toner 92 having a polarity opposite to the toner 93, from which the image on the recording material 91 is formed, is held on the recording material 91, thus preventing a defect caused by the opposite-polarity toner 92 sticking to the pressure roller 32.
