Abstract: Four mounting units are linearly disposed in a machine body of an image forming apparatus. First and second platen covers that differ from each other in weight also differ from each other in interval between support units. The first platen cover can be mounted on the machine body using the mounting units, and the second platen cover can be mounted on the machine body using the mounting units.

Abstract: An image forming apparatus includes a main body portion having on an upper surface thereof a platen glass on which a document is placed, a pressing plate portion openable/closable with respect to the upper surface of the main body portion, and an operation unit enabling performance of an open/close operation of the pressing plate portion by hand. The operation unit includes a first operation concave portion formed on the pressing plate portion side and a second operation concave portion formed on the main body portion side; and the first operation concave portion and the second operation concave portion are combined to form one opening when the pressing plate portion is closed.
