摘要： According to an aspect of the invention, an image forming apparatus includes an apparatus body, a sound absorbing device utilizing a Helmholtz resonator, and a hinged exterior cover operable to open and close relative to the apparatus body. The hinged exterior cover is a hinged cover configured to pivot about a pivot shaft arranged at a lower end portion of the hinged exterior cover. At least a part of the hinged exterior cover has a multiplex structure made by overlaying a plurality of plate-like members on one another. The sound absorbing device is formed by utilizing space between two plate-like members of the plurality of plate-like members making up the multiplex structure as a cavity of the Helmholtz resonator.
