Abstract
An image forming apparatus includes an image bearing member and a charging member that electrostatically charges a surface of the image bearing member. Control is performed for increasing a voltage to be applied to the charging member in a stepwise manner so that the voltage becomes higher than when the image bearing member passes through a region where the image bearing member faces the charging member in a previous rotation, the control being performed as the image bearing member rotates while a single image region worth of image is being formed in an image region that is longer than a length equivalent to one rotation of the image bearing member in a rotational direction of the image bearing member.
