Abstract
An image forming apparatus includes a rotatable image bearing member, a charging member, a developing member, a transfer member, a transfer voltage applying portion, and a recording material charging member. The recording material charging member is provided on a side upstream of a transfer nip with respect to a conveying direction of a recording material that is nipped and conveyed through the transfer nip and is capable of contacting an image forming surface, which is a surface of the recording material onto which a toner image is transferred, conveyed toward the transfer nip, and capable of charging the image forming surface to the same polarity as a predetermined polarity by triboelectric charge. A contact portion of the recording material charging member that contacts the recording material is movable in a direction crossing a surface of the recording material at a position where the recording material opposes the recording material charging member.
