Abstract
An image forming apparatus includes: an image holder that holds an image; a transfer unit that includes a transfer member being rotationally driven and forming a pressing portion between the transfer member and the image holder, and that presses a recording medium under transportation at the pressing portion so as to transfer the image held by the image holder onto the transported recording medium; and an adjustment unit that adjusts drive torque for the transfer member by changing the drive torque from a first adjustment state to a second adjustment state, either when a leading edge of the recording medium reaches the pressing portion or when a trailing edge of the recording medium leaves the pressing portion.
