ABSTRACT:
The present invention provides an image forming apparatus comprising an image bearing member for bearing a toner image, a movable intermediate transferring member, a first charging member for charging toner on the intermediate transferring member when it is applied with a voltage including an AC component, and a second charging member for charging toner on the intermediate transferring member when it is applied with a DC voltage, the second charging member being located on an upstream side of the first charging member with respect to a moving direction of the intermediate transferring member, wherein a toner image on the image bearing member is temporarily transferred to the intermediate transferring member and then transferred to a transfer material.
