Especially, the lower frame 78 forms a transfer material feed path and has a large number of ribs 124 parallelly arranged in a direction crossing a paper feed direction at a right angle. Said ribs are also integrally molded. A large number of air holes 123 are opened in the ribs which are, among other ribs, positioned under the toner recovery tank 57 of a photosensitive body unit 58. Further, a paper delivery guide plate 44 is also integrally molded along with the lower frame 78 and a paper delivery guide member 42 is fixed to the side surface 47c of an upper unit frame 47. The paper delivery guide member 42 is also molded from the synthetic resin, and a large number of air holes 125 are provided to the lower part of said member 42.
