Abstract
An image forming apparatus includes an image bearing member, a charging member, disposed so as to be contactable with the image bearing member, for charging the image bearing member with a peripheral velocity difference between the charging member and the image bearing member, and a controller for variably controlling the peripheral velocity difference at the time when an area which becomes an image forming area of the image bearing member is charged by the charge member.
