An image forming apparatus includes an exterior cover, a connector, and an upper exterior member disposed above the exterior cover. The upper exterior member includes a groove portion and projections. In the upper exterior member, the groove portion is formed so as to extend from a first end closer to the connector to a second end closer to one of left and right side ends of the exterior cover. The projections are formed so as to project upward from a lower edge portion of an opening of the groove portion. A cable connected to the connector is inserted in the groove portion. The projections prevent the cable from being dropped from the groove portion.
