An image forming apparatus including: an image bearing member configured to bear the toner image; a transfer element configured to transfer the toner image to the sheet; a first application element configured to apply a transfer voltage to the transfer element; a separator configured to separate the sheet from the image bearing member, the separator including a separation electrode configured to discharge an electrical current and the separation electrode including first and second separation electrodes aligned along the transfer element; and a partition configured to project between the transfer element and the separator so as to allow a current to flow from the transfer element to the first separation electrode while the partition suppresses a current flowing from the transfer element to the second separation electrode.
