Abstract: A contact member comes into contact with a back surface of a recording material between a nip portion and a transfer portion in a conveyance direction of the recording material. The contact member is capable of being located at a first position, a second position, and a third position. A detection unit detects a position of the contact member so that the detection unit can detect the first position, the second position, and the third position. The contact member reaches the third position by being biased by the recording material from the second position.

Abstract: An image forming apparatus includes: an image forming portion configured to form a toner image on a sheet; a first rotatable member and a second rotatable member which are configured to form a nip therebetween for heating the toner image formed on the sheet by the image forming portion; a separation member configured to separate the sheet in contact with the second rotatable member; a moving mechanism configured to move the separating member so that the separating member is movable to a contact position contacting the second rotatable member and a spaced position spaced from the second rotatable member; and a controller configured to control an operation of the moving mechanism. The controller moves the separating member from the spaced position to the contact position by the moving mechanism when an image forming process is interrupted in a state in which the separating member is in the spaced position.
