To suppress intrusion of foreign matter into an apparatus body while releasing heat generated by an image heating means and air containing vapor to the outside of the apparatus body.
An opening/closing member 30 has: a both-sides conveyance guide 20 constituting a part of the interior surface of the apparatus body in a closed state; and a top exterior part 62 constituting a part of exterior face of the apparatus body above both-sides conveyance guide 20. A guide vent 65 provided to both-sides conveyance guide 20 and a top exterior vent 64 provided to the top exterior 62 are provided so as not overlap, when viewed from a vertical direction in the closed state of the opening/closing member 30. The opening/closing member 30 has a wall 66 provided on the upper surface 20a of both-sides conveyance guide 20, opposite to the top covering 62. The wall 66 is disposed around the guide vent 65 and suppresses the intrusion of foreign matter into the guide vent 65 when the opening/closing member 30 is opened.
