Abstract
An image forming apparatus includes a transfer unit having a conducive roller member formed with a conductive elastic body on an outer peripheral surface of a shaft of the conductive roller member for transferring, to a recording medium, development images formed on an image carrier based on a transfer voltage applied thereto, a voltage application unit for applying the transfer voltage to the transfer unit; a voltage control unit controlling the transfer voltage to be applied from the voltage application unit to the transfer unit, and a temperature measuring unit measuring shaft, temperature of the conductive roller member, wherein the voltage control unit controls the transfer voltage applied to the transfer unit based on the shaft temperature measured with the temperature measuring unit.
