Abstract
Certain embodiments provide a transfer apparatus, which including: an conductive intermediate transfer member; a transfer section configured to secondarily transfer a toner image onto an image receiving medium in a constant current system; a conveyance section configured to convey the image receiving medium; and a high voltage transformer configured to apply a bias to the transfer member, wherein the sum of the products of the volume resistivities [Ω·cm] and the thicknesses [cm] of the intermediate transfer member and the transfer member is equal to or greater than 3.6×10Ω·cm, and the conveyance speed V[mm/s] of the image receiving medium={the output upper limit value A[V] of the absolute value of the voltage output from the transfer polarity side of the high voltage transformer}×0.009.
