Patent attributes
An image forming apparatus including a compact waste toner storage device in which waste toner can be evenly stored. The image forming apparatus includes a waste toner tank to store the waste toner that is collected from a cleaning member to remove the residual waste toner on an image carrying body, and a vibration unit provided inside the waste toner tank to prevent the waste toner from accumulating unevenly. Because the vibration unit is provided inside the waste toner tank, the apparatus can be manufactured compactly. Also, because a coil spring and a stopper are used in the vibration unit, the vibration unit does not take up much space in the waste toner tank. Further, much more waste toner can be stored in the waste toner tank, despite having a same size as a conventional waste toner tank.
