Abstract:
An image forming apparatus, comprising:an image bearing body; transferring means for transferring an unfixed toner image on said image bearing body to a recording medium; fixing means for fixing the unfixed toner image on the recording medium to the recording medium, the fixing means including first and second fixing members for conveying the recording medium while nipping the recording medium between the first and second fixing members; voltage applying means for applying a voltage to the second fixing member which does not come in contact with the unfixed toner image of said fixing means; and charge elimination means for eliminating a charge on the recording medium before the unfixed toner image is fixed by said fixing means; wherein a recording medium of a maximum size at least extends from said charge elimination means to said fixing means, wherein said voltage applying means comprises a first power source and a first resistor connected in series to said first power source and applies a voltage to said second fixing member from said first power source through said first resistor, wherein said charge elimination means comprises a second power source and a second resistor connected in series to the second power source, and applies a voltage to the recording medium from said second power source through said second resistor, and wherein a voltage value (V0) of said first power source, a resistor value (R0) of said first resistor, a voltage value (V1) of said second power source and a resistor value (R1) of said second resistor, have a relation of V0Â·R1>V1Â·R0.
