An image forming apparatus includes a transfer unit, a contact unit, and a constant-current controller. The transfer unit nips a recording medium using an image retaining unit and a transfer member and generates a transfer electric field in a transfer region therebetween so as to electrostatically transfer the image onto the recording medium. The contact unit is provided upstream and downstream of the transfer region in a recording-medium transport direction and comes into contact with the recording medium while the recording medium passes through the transfer region, so as to function as an electrode leading to a ground. The constant-current controller performs constant-current control on a transfer current to be fed to the transfer region by using a transfer voltage when the recording medium is a low-resistance recording medium having a predetermined resistance value or lower or having an electrically-conductive layer along a medium base surface.
