Image forming apparatus

An image forming apparatus, comprising:

• a main body formed with an exposure opening through which an inside is exposed to an outside;
• a fixing unit which is arranged along a first direction on an inner side of the exposure opening in the main body, and includes a fixing member which is heated and a pressure member which biases a sheet toward the fixing member;
• a heating unit which is arranged in the main body along the first direction while being arranged next to the fixing unit in a second direction orthogonal to the first direction, and includes a heater which heats the fixing member;
• an operation member capable of moving by being operated;
• a unit movement mechanism which is arranged on a side opposite to a side of the fixing unit in the second direction with respect to the heating unit in the main body, and causes the heating unit to move between a reference position provided along the fixing unit and an evacuation position farther away from the fixing unit than the reference position in conjunction with a movement of the operation member;
• and
• a pair of fans which are arranged with an interval provided therebetween in the first direction on a side opposite to a side of the heating unit in the second direction with respect to the unit movement mechanism in the main body, and blow air toward the heating unit, wherein
• when the heating unit is present at the evacuation position, the fixing unit can be drawn out from inside the main body along the first direction,
• the heating unit includes a ventilation duct including a hollow portion formed along the first direction, a pair of inflow openings which are formed opposite to the pair of fans and are in communication with the hollow portion, and a discharge opening which is formed between the pair of inflow openings in the first direction and is in communication with the hollow portion, and
• the unit movement mechanism includes
• a unit coupling member which is coupled to the heating unit while a gap is provided between the unit coupling member and the discharge opening at a position between the pair of inflow openings in the first direction, and
• a link mechanism which transmits the movement of the operation member to the unit coupling member.
