An image forming apparatus includes an image forming section, a body housing, a protruding housing, a light diffusing portion, a light source, a light guide path, and a control unit. The image forming section performs image formation on a sheet. The body housing is formed by a box body with a top surface, and contains the image forming section. The protruding housing is located on the top surface, and has a top portion protruding upwardly above the top surface. The light diffusing portion is located in or near the top portion of the protruding housing. The light source is located inside the body housing or the protruding housing, and emits light. The light guide path guides light emitted by the light source to the light diffusing portion. The control unit controls illumination of the light source based on the information related to the image formation.
