ABSTRACT:
A sheet discharge roller has a contact portion in contact with a feed roller and a noncontact portion not in contact with the feed roller. The sheet discharge roller includes a kick-out unit having a projected portion and a recess portion on one end of the noncontact portion in the circumferential direction. A reverse roller also has a contact portion in contact with the feed roller and a noncontact portion not in contact with the feed roller. The reverse roller includes a large-diameter portion on its one end in a direction opposite to a direction of the kick-out unit. The large-diameter portion has a diameter larger than a diameter of the contact portion.
