<p>An image forming apparatus comprising: a charging member (110) that receives application of a charge potential to charge an image bearing member (100); an exposing member (120) that exposes the image bearing member (100); a developing member (130) that receives application of a developing bias to form a toner image on the image bearing member (100) based on a state of the exposure; a transfer member (140) that receives application of a transfer bias to transfer the toner image formed on the image bearing member (100) to a recording medium; a transfer bias applicator (240) that applies a predetermined voltage to the transfer member (140); a current detector (250) that detects currents flowing through the transfer member (140) upon application of two or more kinds of voltages from the transfer bias applicator (240) to the transfer member (140); and a voltage determination unit (300) that determines a charge potential and a developing bias to be employed in image formation based on a predefined voltage decision table and a combination of the voltage applied by the transfer bias applicator (240) and the current detected by the current detector (250).</p> |
