1. An image forming apparatus comprising:
an optical box including a light source configured to emit light to an image bearing member;
a housing provided with a discharge opening through which a recording material is to be discharged, wherein the housing includes a cover provided as an end surface of the housing on a downstream side in a discharge direction in which the recording material is discharged through the discharge opening, the optical box is provided inside the housing, and the cover is disposed downstream of the optical box in the discharge direction and extends in a vertical direction; and
a circuit board configured to convert an alternating current supplied from an external power source into a direct current and supply power to the light source,
wherein the circuit board includes a plurality of electronic components and a wiring board configured to electrically connect the plurality of electronic components,
wherein the circuit board is disposed in such a direction that a surface of the wiring board on which the plurality of electronic components is mounted intersects the discharge direction and extends along the cover,
wherein the wiring board is provided between the cover and the optical box in the discharge direction, and
wherein, when viewed in the vertical direction, the optical box and the plurality of electronic components partially overlap each other.
