a first member that rotates;
a second member that rotates, the first member or the second member having a recess, the first member and the second member forming a nip area therebetween and transporting a recording medium while nipping the recording medium in the nip area;
a gripping member that grips the recording medium;
a separating member that separates the recording medium having passed through the nip area from the first member or the second member; and
a control mechanism that controls opening and closing of the gripping member and movement of the separating member such that the gripping member is opened so as to release the recording medium in a state in which the gripping member is located in the recess, and the separating member lifts the recording medium from a state in which a tip of the separating member is located in the recess, wherein:
the control mechanism includes a cam follower and a cam fixed to an outer circumferential portion of the second member for controlling the movement of the separating member, and
contact between the cam follower and the cam controls the separating member to enter the recess by rotation of the second member.
