An image forming apparatus has an image bearing member, an image forming unit for forming a toner image on the image bearing member and having a first charge member for charging the image bearing member, a rotatable intermediate transfer member onto which the toner image on the image bearing member is transferred at a first transfer position, the toner image on the intermediate transfer member being transferred onto a transfer material at a second transfer position, and a second charge member for charging residual toner remaining on the intermediate transfer member, the second charge member charging the residual toner on the intermediate transfer member with polarity opposite to charging polarity of the first charge member for charging the image bearing member, after the toner image is transferred from the intermediate transfer member to the transfer material. At the first transfer position, an electric field for transferring the residual toner on the intermediate transfer member charged by the second charge member onto the image bearing member is generated, and a charging area of the second charge member in a longitudinal direction thereof is disposed internally of a longitudinal charging area of the first charge member.
