An image forming apparatus includes a main body; an operation panel coupled to the main body to rotate between a storage position and a use position; a stopper positioned on the operation panel; a stopper support unit, located on a rotation trajectory of the stopper with interference, which has a blocking position to block a rotation of the operation panel to the use position and the storage position, and a non-blocking position to allow a rotation of the operation panel; an elastic member to generate an elastic force in a direction where the stopper support unit is located in the blocking position; and an operation member to rotate the stopper support unit to the non-blocking location.
