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.
