Abstract:
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.

Claim (Index 11):
An image forming apparatus comprising:\n transfer means for nipping a recording medium by using image retaining means, which retains an image by using a charged imaging particle, and a transfer member and that generates a transfer electric field in a transfer region between the image retaining means and the transfer member so as to electrostatically transfer the image retained by the image retaining means onto the recording medium; contact means that is provided at an upstream side and a downstream side of the transfer region in a transport direction of the recording medium and that 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; and constant-current control means for performing constant-current control on a transfer current to be fed to the transfer region by using a transfer voltage applied from a transfer power source in a condition in which 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.
