An image forming apparatus includes a carriage on which a recording head of an ink-jet system is mounted, a carriage drive mechanism to drive the carriage, a sheet transport mechanism to transport a sheet in a specified direction, a main power-supply unit, and an auxiliary power-supply unit. The carriage is moved in a direction orthogonal to the transport direction of the sheet by the carriage drive mechanism. The image forming apparatus includes a cap movable in a direction of coming in contact with the recording head and in a direction of separating therefrom, and a cap drive unit to move the cap. The auxiliary power-supply unit supplies electric power to the cap drive unit at a time of interruption of the main power-supply unit.
