Image forming apparatus and the fixing device

2013 
PROBLEM TO BE SOLVED: To provide a fixing device capable of preventing paper sheets after a fixing process from being electrostatically attracted to each other and to provide an image forming apparatus.SOLUTION: An image forming apparatus (fixing part 60) includes fixing surface side members (a fixing belt 62a, a heating roller 62b, and a fixing roller 62c) arranged on the fixing surface side of the paper sheet on which a toner image is formed, a rear surface side support member (a pressure roller 62d) forming a fixing nip NP for holding and conveying the paper sheet in a press-contact state with the fixing surface side members, and voltage application parts (a high voltage power supply 90 and a pair of conveyance rollers 92) applying a voltage having a polarity reverse to that of the surface potential of both surfaces of the paper sheet after passing through the fixing nip NP to both the surfaces. Thus, the voltage having the polarity reverse to that of the surface potential of both surfaces of the paper sheet after passing through the fixing nip NP is applied to both the surfaces, so that an electrical charge charged on both surfaces of the paper sheet is sufficiently removed in comparison with a case where only one surface is discharged.
