Abstract
An image forming apparatus includes an image bearing member; a stretched rotatable belt member; a transfer device for forming a transfer portion where a toner image is transferred from the image bearing member onto a recording material carried and conveyed on the belt member; a separation roller capable of separating the recording material from the belt member; a push-up device capable of pushing up a belt surface locally with respect to a widthwise direction of the belt member to separate the recording material from the belt member; and an execution portion for executing, when an abnormality occurs during an image forming operation, an operation in a stop mode in which the belt member is, after the image forming operation is stopped, rotated in a push-up state of the push-up device and then the rotation of the belt member is stopped.
