PURPOSE:To provide an image forming device preventing the soundwave of noise generated in a device from leaking out of the device by a soundproof cover. CONSTITUTION:In the image forming device at least whose external wall of a noise generating part is covered with the soundproof cover, the soundproof cover 3 is formed of a laminate body alternately laminated with solid layers 1 made of different materials and air layers 2. The adjacent solid layers constituting the laminate body are joined with a viscous material 4. |
