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.
