PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing image defects due to discharge, and leakage of transfer current to peripheral members.SOLUTION: An image forming apparatus comprises: an intermediate transfer belt that is laid over a plurality of rollers, and conveys a toner image on an outer peripheral surface; a secondary transfer member that secondarily transfers the toner image on the intermediate transfer belt to a recording medium; an opposing member that is brought into contact with an inner peripheral surface of the intermediate transfer belt to be opposite to the secondary transfer member; and first voltage applying means for applying a first transfer bias voltage to the opposing member and second voltage applying means for applying a second transfer bias voltage having a polarity opposite to that of the first transfer bias voltage, at a secondary transfer position where the secondary transfer member is in contact with the opposing member across the intermediate transfer belt. The image forming apparatus determines a distribution of the first transfer bias voltage applied by the first voltage applying means and the second transfer bias voltage applied by the second voltage applying means at a predetermined secondary transfer bias voltage, on the basis of paper attribute information and/or use environment information on the recording medium. |
