Abstract
An image forming apparatus includes a voltage applying unit that applies a bias voltage for enabling a transfer unit to transfer a developer layer to a transfer medium, the developer layer being retained by an image carrier in accordance with image information; a measuring unit that measures a surface potential of the developer layer; and a setting unit that sets a value of the bias voltage to be applied by the voltage applying unit in accordance with the surface potential measured by the measuring unit, a combined electrostatic capacitance of a surface layer of the image carrier and the developer layer, and an electrostatic capacitance specific to the transfer medium.
