Abstract
An image forming apparatus includes image forming device for forming an image on a recording material, the image forming device including an image bearing member, a charging member for charging the image bearing member and a voltage source for supplying a voltage to the charging member; and determining device for determining a substantial intersection between an actual voltage-current characteristic curve between the charging member and the image bearing member and a predetermined voltage-current curve predetermined for the charging member, and for determining a bias to be applied to the charging member during image forming operation of the basis of the intersection.
