Abstract: An image forming apparatus includes an operation display movably mounted on a mount face and a linkage defining a movement range of the operation display. The linkage includes a first arm coupling a part of the mount face with a part of the operation display and a second arm coupling another part of the mount face with another part of the operation display. The operation display moves in the movement range in which the operation display does not enter the opening, does not protrude outward beyond the mount face when the first arm and the second arm support the operation display perpendicularly to an installation face of the image forming apparatus where the image forming apparatus is placed, and does not protrude upward beyond a scanner when the first arm and the second arm support the operation display parallel to the installation face of the image forming apparatus.
