摘要:
An image forming apparatus includes an image bearing member; a toner image forming portion for forming a toner image on the image bearing member; a rotatable belt member, stretched by a plurality of stretching members, for carrying and conveying a recording material; a transfer member for transferring the toner image from the image bearing member onto the recording material; a bias applying portion for applying a bias for transferring the toner image from the image bearing member onto the recording material; a push-up member for pushing up the belt member from an inner surface side of the belt member, perpendicular to a recording material conveyance direction; and an execution portion executing an operation in which the recording material is separated from the belt member by a push-up operation, which is performed, during rotation of the belt member, before the bias is applied to the transfer member.
