Image forming apparatus including an angle-adjustable operating member

An image forming apparatus comprising:

• a top exterior member having a holding recess, the holding recess including at least a bottom wall and a side wall, the bottom wall having a first through hole and a first protrusion therein, the first protrusion including a first fastening member insertion hole that opens toward the side wall of the holding recess;
• and
• an operating member on the top exterior member, the operating member configured to be operated by an operator to give an instruction on operation, and the operating member including a bottom surface, the bottom surface having a second protrusion and a third protrusion therein, the second protrusion including a second fastening member insertion hole that opens toward the bottom wall of the holding recess, and the third protrusion including a second through hole that opens toward the side wall of the holding recess,
• wherein,
• the operating member is configured to be selectively fixed to the top exterior member in one of a first posture and a second posture,
• if the operating member is in the first posture, a fastening member is inserted into the first through hole and the second fastening member insertion hole of the second protrusion so that the operating member is fixed to the top exterior member such that the operating member is inclined by a first inclination angle with respect to the top exterior member while the operating member is being held by the holding recess, and
• if the operating member is in the second posture, the fastening member is inserted into the first fastening member insertion hole and the second through hole so that the operating member is fixed to the top exterior member such that the operating member is inclined by a second inclination angle different from the first inclination angle with respect to the top exterior member.
