To provide an image forming apparatus that prevents the generation of unstable electrical field in a conveyance path from a transfer part to a fixing part to prevent the occurrence of an abnormal image such as background stains due to toner dust.

An image forming apparatus comprises: a conveyance belt that conveys a recording medium from a transfer part that transfers a toner image developed by an electrostatic photographic system on a recording medium by allowing the recording medium, which is held by a transfer nip, to be subjected to a transfer electrical field, to a fixing part that fixes an unfixed toner image carried by the recording medium. The surface resistance of the conveyance belt is set to be not more than the surface resistance of a transfer roller that holds a recording medium.
