Abstract
An image forming apparatus includes an image bearing member and a transferring member for transferring a toner image on the image bearing member onto a recording material in a transferring portion of the image forming apparatus. When the recording material is not present in the transferring portion, a voltage is applied to the transferring member, and on the basis of an electric current then flowing in the transferring member, a voltage applied to the transferring member, when a non-image portion of the image bearing member is in the transferring portion, is controlled.
