Abstract
Heat exhaust holes are provided in a unit frame at positions just above respective imaging units. An exhaust fan causes air heated at developing elements to be exhausted outside an apparatus via heat exhaust ducts and a common duct. The heat exhaust holes are formed in different sizes depending on a position of the imaging unit. The closer the position of the imaging unit is, the larger the heat exhaust hole provided above the imaging unit is.
